Bloomburrow Promos

A permanent that loses all abilities because of Azure Beastbinder's last ability may later gain abilities.

Azure Beastbinder's last ability overwrites all previous effects that set the creature's base power and toughness to specific values. Any power- or toughness-setting effects that start to apply afterward will overwrite this effect.

Effects that modify the creature's power and/or toughness, such as the effect of Overprotect, will apply to the creature no matter when they started to take effect. The same is true for counters that change its power and/or toughness and effects that switch its power and toughness.

Once Azure Beastbinder has been blocked, increasing the blocking creature's power to 2 or greater won't cause Azure Beastbinder to become unblocked.
