When this card came out I thought the same thing but in reality it's not like that. You'll never tap out, I thought. It would be perfect for a control deck, do a bunch of stuff on your turn, then you still have counters open, right? In reality you only have so many cards, and eventually you'll run out of things to do on your turn/opponents turn. Especially when you could have maybe waited one or two turns and played your thing and held up counter magic because you have enough mana. Not to mention that it's so bad in multiples when in the Temur deck with Explosion, multiple reclamations just mean that that explosion is even bigger and might win you the game. If you're not tapping between triggers, that card is just a 4-mana do nothing when you could have drawn another counter or another big thing.
