Flying (This creature can't be blocked except by creatures with flying or reach.),
trample (This creature can deal excess combat damage to the player or planeswalker it's attacking.)
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.
