The Glass Triplets

Whenever an opponent draws their third card
each turn, that opponent may have you draw a
card at the beginning of your next upkeep. Otherwise, you may make a copy of any
enchantment you control.
At the beginning of your end step, if you've
drawn at least three cards this turn, create a
token that's a copy of The Glass Triplets except
it's not legendary and its base power and
toughness is 0/1.
