Shrapnol, Etherium Hellkite

Trample, Flying, Deathtouch, Haste, Indestructible
When Shrapnol enters the battlefield, you may
search your library for any number of colorless
spells with different names and you may cast
without paying their mana cost.
When Shrapnol attacks or blocks, put six -1/-1 counters on all colored creatures and Shrapnol
gets that many +1/+1 counters.
