Natures Defender

At the beginning of every upkeep, create a 1/1
green Saproling creature token.
As long as you control 10 or more creatures, creatures you control have +2/+2 and trample.
When a token creature you control dies, search
your library for a basic land card, then put it
onto the battlefield tapped, shuffle afterwards.
Natures Defender has 45 life, 1 power, Lifelink,
and Protection from creatures with Haste.
