The Sisters of the Glade

When The Sisters of the Glade enter the battlefield, create two 0/1 green plant creature
tokens.
Spells you cast have Convoke (Your creatures can
help cast this spell. Each creature you tap while casting
this spell pays for {1} or one mana of that creature's
color.)

We will shield eachother from Izzet's storms, Golgari's
Rot and Azorius' Tyranny.
