The Flower Game

Solar, Arc, Solar, Stasis, Strand Affinity
Whenever you cast a spell play land or untap
or draw you may search your library for any card
and play it, if it's a land put it onto the battlefield
each opponent does the same thing.
It gains protection from everything, and
"when this card is put into a graveyard you lose"
at the beginning of your next turns end step sacrifice that card.
