Can you tell me the rulings for Dragonkin Berserker?
user
0. Once you announce that you’re activating a boast ability, no player may take actions until the ability has been paid for. Notably, opponents can’t try to change the activation cost by removing your Dragons.
1. The cost reduction applies only to generic mana in the activation costs of boast abilities you activate. It can’t reduce requirements of specific colors of mana.
