Irion, Verdant Broodlord

Trample, Vigilance, Reach
Irion, Verdant Broodlord enters the battlefield with
X +1/+1 counters on it.

Whenever you cast a spell or activate an ability with X in its mana cost, create a green Hydra creature token with trample that has base power and toughness X/X. Then put an additional +1/+1 counter on each Hydra you control.

At the beginning of your upkeep, if you control three or more Hydras, distribute X +1/+1 counters among any number of Hydras you control, where X is Irion’s power.
