outdamaging amargios can certainly happen, as can lobotomizing otyughs...
But as for Pulverizer destructions, which protect this card as well-two counters, Enchant artifact from
, or Graviton Scavengers.
My thought, is that this card offers potentially immense returns, especially considering it can work when your creatures target stuff-it doesn't have to be simply reacting to enemies-
basically, just one of these with an otyugh, the creature gets +2/+2, which adds up very fast.
as for amargios-That's more iffy, to be honest, but with 25/30 HP, It's going to take more than a few shots to bring it down, and in the meantime it's also getting increasing attack power as well.
I can say that it's iffy if it will earn back it's cost without a combo, but the combos available seem to have worrisome potential.
And considering that you can stack it for more gains per contact...
That's why I'm worried, it activates whenever your creatures use a targeting ability, or is targeted by another creature.
