Arceus, the Creator

Indestructible, Hexproof, Multitype.
At the beginning of your upkeep, you may
transform Arceus. It keeps its +1/+1 counters.
Final Judgement: When attacking, you can make
Arceus get one loyalty and one +1/+1 counters.
If you do, next turn Arceus can not transform,
and can not activate this ability.
