The wording is wrong, it should be "Generate
each round. 4
: Storm (Sacrifice) Deal 3 damage to target creature." for the unupped one and "Generate
each round. 4
: Storm (Sacrifice) Deal 3 damage to all enemy creatures.".
Unupped one should cost 2
and upped one 5
imo, since the card pays for itself after just 2 turns and is a RoF for Aether.
