Magic The Gathering Cards of types 'Avatar' and 'Leviathan'

Flying Whenever Sin enters or attacks, exile a permanent card from your graveyard at random, then create a tapped token that's a copy of that card. If the exiled card is a land card, repeat this process.

Flying, trample As Sin enters, remove all counters from any number of artifacts, creatures, and enchantments. Sin enters with X +1/+1 counters on it, where X is twice the number of counters removed this way. When Sin dies, put its counters on target creature you control, then shuffle this card into its owner's library.
