Yunbuzzela, Hive Mother

Flying
Whenever a land enters the battlefield, its
controller creates a 1/1 green Insect token with
Flying and Deathtouch on the battlefield under
their control.
At the beginning of your upkeep, you gain
life equal to the number of Insect tokens on the
battlefield.
"Nothing is more valuable than the Hive...except for
the queen, of course."
