Synthesix

Synthesix enters the battlefield with a number
of counters of your choice on it equal to the
amount of mana you paid to cast it. You can
choose the counters from among Reach, Toxic, Deathtouch, Menace, Trample, Lifelink,
or +1/+1 counters, and you can choose the same counter more than once.
The first time a Plant creature card or a land card leaves your graveyard each turn, proliferate.
