I think "When this first moves" cards should be erased, here's why.

Spider-Man 2099: bet you forgot this existed, right? To help you remember, it's a 5 cost 9 power card, that destroys an enemy card the FIRST time it moves. Oh please. It's FIVE COST. Gambit, Gladiator, cards that destroy enemy cards are SO much more powerful both at 3 cost. From a player who still uses it(shocking i know) I can barely move it ONCE per game, there is absolutely NO need for it to work only for the first time. Sure, people can figure out powerful combos but it's not like they don't do with other cards, I genuinely don't get the difference.

Red Wing: I admit I have lot less knowledge of this card, as I don't own it, and my post is mostly focued on Spider-Man 2099. But I felt like I should mention this too. It's a 3 cost 4 power card. Brings down a card to the old location the first time it moves. Sure, a powerful ability at 3 cost. Make it a 4/2, and I believe it would be unnecessary to have the "first time it moves" ability.

I know this isn't like a deep dive or anything, just my thoughts. Opinions are welcomed. Just stay civil please.
