"Gravebone: 4SE: Return any ally from your discard pile to play."
if a PB return, he can use his ability this turn and attack?

suggestion:
Elementalis: 3SE holy shield effect.
you can summon 5cc ally and this ability make supernova useless.
it will make elementail survive in mid-late game.

revert Discharge Energy to first version

-1 Jericho user idea.

if elementail control board, there are 2 cards can help health for him,dont use any SE to do such useless thing.

not a good idea.
if you control board you needn't Sacrifice any ally to gain so little health.
if you can't, (most time i know), you Sacrifice what?3cc ally+2cc life infution + 4SE add 9 health and...

yes, how to do a ally attack and i use SE on him, haste and attack again?

if we suppose SE == cc;

what do to Elementalis? you mean Elementalis can control board easily? uesless ability.
a high defence ally mean high cc, high cc + high SE to do such a stupid thing?
