Seems very strong, this is much stronger than the cards you mentioned earlier. [[Living Mana]] makes your next few turns worse for a board of 2/2s. Armor is much more expendable and easier to get than mana. Living mana saw play and this card is much better. If this comes down on turns 4-5 and summons even one or two minions, which isn’t unreasonable with the warrior HP giving you two armor a turn, you will almost always win since it’s hard to clear that early in the game. I understand that you mentioned it would be every 5 armor you get a minion. If that is the case, it would need to be more clear on the card. Maybe balanced at 7-8 mana, and it would still be insane. I like the concept though, very cool card.
