I’ve tried using this card in a number of decks, and while I think it is decently playable, it really isn’t as great as it may seem at first, as it has a number of disadvantages:
- May not be reliable early in the game when you don’t always have an ally around – and when you have no allies is probably when you most need the toughness to defend yourself
- Conversely, by the time you have tons of allies and can easily play this card, you may be pretty good at chump blocking anyway and happy to cycle through your ally slots to play a new ally
- Using this card on an ally to suck up an attack exhausts that ally so it can’t be used next turn. Often you need your allies to deal with heavy pressure from the villain and don’t want to delay their use by an extra turn.
- If you don’t need the defense quite yet, the ally you put it on still can’t do anything without “wasting” the Tough card blocking consequential damage.
- Ready for Action looks amazing compared to Invulnerability, costing 3 instead of 1. But Invulnerability is way overpriced so this comparison is meaningless.
- Most notably, the main alternative to this card is that for only a single extra mana you can already get a cheap ally who can also absorb an attack, while also being more flexible and doing something else useful, like a 2 damage attack, and without suffering the disadvantages listed above.
Ready for Action does have some advantages compared to a chump blocker, works better against Overkill (which is more common than Pierce) and doesn’t hit the ally limit, and Ready for Action has the alternate use of playing it to cancel the consequential damage of a powerful ally’s action, and of course it is easier to afford while playing other cards, so it is OK, it was just surprising how often I drew it and didn’t want to play it.
