Hulking Tinker Core

When Hulking Tinker Core dies, create two 1/1
white Tinker Toy artifact creature tokens. Each
Tinker Toy created this way enters the battlefield
with a +1/+1 counter and has "When this token
is destroyed, create two 1/1 white Tinker Toy artifact creature tokens."
"When one is destroyed two more take its place.
It's a never ending cycle of fun."—
Ezex, The Tinkerer
