Does the +1 stack, IE you move it again and it gains another one? Or is it static?
The + 1 stacks permanently.
So it goes +1, +1, +1, and so on? That might get out of hand, esp. with the upgraded, but then again, it is an activated ability so that might counter balance it. Also rampant creature playing would, or cards that spawn other cards.
That being said, however, the ability looks nice. You may want to start off Bishop with 0_1, so that it doesn't attack straightaway and start gaining attack. Also to reduce the effectiveness of epinephrine on top of this; move bishop ONCE and it gets a massive boost.
True Pawn can keep adding + 1, yes it can get out of hand.
But the thing is elements have lots of better cards and comboes to create more impressive damage.
The pawn needs so much time to be able to generate that kind of destruction damage to kill your opponent.
How does one select which ability to use?

After you click on Pawn, two shiny spots will appear, one on the next slot and one on the back slot,
click either to advance Pawn to that slot, same as chess.
Im guessing Pawn's grow ability is too strong,
but Pawn's actually requires strategy,
Lets say you put Pawn into your battlefield,
then you put Forest Spirit into your battlefield,
now your Pawn cant advance to the next slot to get that +1/+0 bonus,
the Pawn moves is blocked, its like chess.
