I'm getting the growing sense that the Louisiana Lion is held in far higher esteem than he deserves. Even in my Jenny Barnes deck, he never quite managed to carry his own tremendous weight. In my "Skids" O'Toole and Finn Edwards decks, he might as well have been a blank card for all the good he did.

First of all, a fourth action will not make an investigator 33% more effective - not even close. Investigators run on cards and resources, and any kind of "once per round" economy the investigator has (including the usual card and resource during upkeep) will be spread much more thinly over four actions rather than three - fewer resources to pump into Hard Knocks, fewer skill cards to commit to tests, and fewer charges of Flashlight, compared to the number of actions you have in which to use them. You could always use the extra action to draw a card or gain a resource, but if all you want is some drip economy, why not just run Lone Wolf or Pickpocketing, which pay for themselves much more readily?

Second, unlike most of the other pricey allies, Leo doesn't give any skill bonuses - you'll be taking more actions, but you'll waste a lot more actions on failed skill tests. For example, Dr. Milan Christopher's +1 makes the actions you have that much more efficient, and he's cheaper to put into play and serves as an (admittedly slow-to-wind-up) economic engine. See also Peter Sylvestre, Cat Burglar, and of course Beat Cop.

Third, by occupying the ally slot, he prevents you from playing those other aforementioned allies.

Fourth, he's crazy-expensive, which makes him awkward to play in most situations:

• Getting him out early costs one more than your entire starting resource pool. Unless you're lucky enough to draw him alongside Hot Streak, this is a crippling opportunity-cost; he's going to be your only significant asset for the first few rounds.

• Getting him out midgame has a similar (but more manageable) opportunity cost, but he takes so many rounds to pay for himself that he may just barely break even by the end of the scenario, and in the meantime you've deprived yourself of the tools that might have rescued you from a dire situation if you had run a different card and not sunk a small fortune.

• Getting him out in the late-game is usually a waste. If you only have a few rounds left, you should be able to spend six resources on something more worthwhile than two or three more actions spread over the remainder of the scenario.

And all of that assumes that you aren't forced to discard Leo early because of an Encounter card, which could be a serious possibility depending on the scenario, especially if he's your only asset in play at the time.

If anything, his relative economy actually gets worse for high-XP investigators. In the Rogue class, Streetwise is a fantastic way to pump skill tests, and it plays better with high-efficiency limited-use cards like Lupara, Deduction, and of course Double or Nothing, not to mention the highly efficient pumped "Watch this!". I'd much rather move once and take two amazing actions than move once and take three mediocre ones.

Therefore, Leo is at his best when paired with cards that can turn actions back into resources (or at least cards), so he can recoup his costs faster. Alchemical Transmutation is a strong combination (provided you have the for it), and Decorated Skull and Burglary are at least situationally useful.

I think the basic principle in play here is that extra actions are generally weaker than optimized actions, and those are more easily achieved with other cards.

I think this card is pretty useful. Now, in multiplayer, taking away the Elder Sign from the group to give Father Mateo +1 Willpower is not the best idea. If Father Mateo is taking a lot of Will tests, it actually isn't that bad of an exchange in a 2-player game; but at higher player counts it does start to hurt the group. More importantly, removing the Elder Sign takes away fun from other investigators and will quickly make you the least popular player on the table. I don't recommend it!

But this card is still fine as a kind of janky Seal of the Elder Sign. Just wait until you need to Shrivelling V a high-fight enemy or Rite of Seeking IV a high-shroud location, or attempt some other similarly high-reward, high-difficulty test, plop down The Codex of Ages, and use it right away. The 1-action, 1-card, 2-resource cost of the The Codex of Ages is easily justified by the guaranteed success on a critical test, and of course Father Mateo's Elder Sign effect will make back some of that anyway. It's a strong play, and I wouldn't use The Codex of Ages for its icons unless I was desperate.

Obviously nice with a teammate's Double or Nothing for e.g. six clues from Rite of Seeking IV. That's a power move.

In solo I would think +1 Willpower would ordinarily be superior to having the Elder Sign in the bag, even considering how useful Father Mateo's Elder Sign is. So you probably want to just play the Codex in advance there, if you have time. This will also make it easier to use the Codex against enemies, something that would otherwise be tricky in solo (but less so in multiplayer).

This is a great card in the core campaign, especially for "The Midnight Masks", but its even better in "Return to the Night of the Zealot", as its still amazing in "Return to The Midnight Masks", but now pretty good for "Return to The Devourer Below" also, as the update has refreshed the need for intellect-based-investigation.

It's particularly great for Pete (as it works with Duke) and Minh, both of whom want to be searching anyway. Wendy's probably down with it too.

This card scales extremely favorably in 4-player games. If you've glossed over the Skull in 2-player (the most common format), but are invited to a 4-player, then do give it another look.

It sadly does clash with the Rosary for Akachi and Sefina, but Ursula, Leo, Wendy, or any of the other Rogues can make good use of it it in a 4-player game. I'm not sure I'd go as far as spending a splash-card for Pete, Rex, etc though.

This card is really very good. Even ignoring the 2x Agility icons, it has lots of play. It's difficult to describe exactly what you would use it for, as its such a tactical card, with its use depending on the situation, but here are a few scenarios where I have found it useful.

• Dropping a weapon or ally from hand, then using the weapon straight away with a bonus.
• Similar to the above, but powering up with a Hot Streak, Emergency Cache, or other card
• Using it as a pseudo-Overpower, by drawing a card, pulling a resource, (or anything else), fizzling the attack and then unloading your weapon
• Using it to drag an enemy to a location, so somebody else can deal with it, similar to Shortcut, except you also get to do something at the end. (Evade the enemy perhaps)?
• Using it as an Unexpected Courage for game-winning checks, possibly even by Engaging a monster you didn't need to
• Using it for a local Dynamite Blast, followed by an attack

Basically, it is often Unexpected Courage + Dodge, all for 0 XP, 0 Resources, and even when it isn't, it can function as a double-Agility.

It's in all my rogue decks, and I rarely want to take it out. It's up there with Elusive, Leo and Lone Wolf as one of the best 0 XP Rogue cards, in my opinion. It doesn't have as much impact, but it's got so much value.

Oh, and the picture is cool too.
