How does this work with dive? I you can double a creatures attack power multiple times a turn this could be painfully OP in a Pegasus + blessing deck
example: a 6/5 Pegasus is hit with this shard, and now has dive for 4

that can trigger multiple times per turn.
for 4

the Pegasus does 12 damage
for 8

the Pegasus does 24 damage
for 12

the Pegasus does 48 damage
for 16

the Pegasus does 96 damage
Basically with 24

, this card, a blessing and a no-upgraded Pegasus you could OTK a FG
There needs to be some sort of exception with dive.
