Whenever Radha’s Firebrand attacks, target creature defending player controls with power less than Radha’s Firebrand’s power can’t block this turn.
Domain — : Radha’s Firebrand gets +2/+2 until end of turn. This ability costs less to activate for each basic land type among lands you control. Activate only once each turn.
Increasing the target creature's power in response to Radha's Firebrand's first ability can cause it to be an illegal target for the ability. However, once the ability has resolved, it won't be able to block even if its power becomes greater than Radha's Firebrand's power.
