yeah, I see what you are saying, I gave it some thought. You need to consider, it doesn't gain the Growth until the delay counter is removed. In other words, it gains only +4|+3 once a turn,
during the time it spends in the 'time bubble' or otherwise delayed. You have to wait for it to get big.
It does have its uses, but with only six gravity pulls, you are better off with armagio or big dragons.
I think it has potential, that is what this is really about, potential. It is weak to several forms of creature control, in particular Entropy, which can mutate it into something else or use maxwell to Paradox it once it is too big. Now a little armor or basilisk blood does go a long way, but if you keep it material to utilize its abilities beyond countering Procrastination, its weak to CC, especially druids and mutation. The key is to kill it early, before it amasses power.
I liked the idea of using it with BB Epi Momentum and Quint, 27|22 like 3 turns after you play it. Thats a five card combo which justifies its brutish power. You wont be able to heal or buff it any further, leave the momentum off it opponent is using turtle or Proc for autogrowth.
What I liked about it was using it in a Sundial Stall and just being able to heal it with Rewind/Eternity. Nice with Crusaders that way
