This card, very plainly, is a piece of crap. Tenacity is known as one of the worst cards that is very well known, because it is in the core set. To start, it takes 3 ER (effective resources) to get out on the table, and then another specific resource () to activate once, get discarded, and ready your hero. To top it off, the art is just meh with a picture of Spider-Man fixing some buildings. I would erase this card's text, "Spend a resources...", and then I would probably still not use it, but it wouldn't be as bad. This card works well with Friction Resistance in Quicksilver's kit, but that is one card in a hero-specific kit. On MCDB most people only put this in decks with Quicksilver or Iron Man. I just like Stick-To-Itiveness (the 'Pool version) better.

Lady Deadpool and Headpool have my vote for the best 'Pool allies because the Amplify icon is generally the easiest to mitigate, at least in solo (stun, confuse, ally block). It does get worse with more players since the villain has more activations per round. You can thwart or attack effectively with Lady Deadpool for as long as she remains in play, and then when you draw a problematic minion, block with her in the next villain phase before the minion even has a chance to activate. A solid card in an aspect with not many options

Kidpool has a strong enough activation that I'm fine leaving him in play for a while, unlike some other 'Pool allies. Trading 2 pierce damage for an acceleration icon is generally in your favor, though it does take many turns to earn back the initial 3-resource investment. If your collection is large enough, there are still probably some basic allies that would be more powerful to play. If you want to lean harder into the 'Pool aspect or are going for the "bad icon" archetype, Kidpool is definitely fine to include.

I think Dogpool's best use is to block twice (possibly 3 times) and clear out. The ability to ATK 1 repeatedly with no consequential damage is not powerful enough imo to outweigh the acceleration icon, but you may get some use out of it in the "bad icon" 'Pool strategy. Dogpool is at least not as disastrous as the hazard icon allies are, but if you are building for power level there are plenty of basic allies I would play over this card.

I really like this card. It is a very solid all rounder card that is good for almost all Cyclops decks. I also really like the art here, except her face is in a very weird expression. The quote is also great showing the bond between Ms. Grey and Cyclops. Ok, so on paper this card is 3 2 2 3 (3 cost, 2 thwart, 2 attack, 3 health). But her response allows her to grab any Cyclops card so it basically goes down to a 2 2 2 3, which is insanely strong with no drawbacks. I almost always play this card when it is in my hand and wouldn't make any changes to it.
