Using Umbral Mantle ´s ability after defending player decleared blockers?

Asked by MarOo 9 months ago

Hi there,

i am not quite sure if this play is legit, so i ask this question here:

Can i boost up my attacking Llanowar Tribe to infinity by using Umbral Mantle AFTER the defending player decleared his blockers / non-blockers? (Background for not doing this beforehand: The defending player in this example would not have decalered Blockers if i attacked with Llanowar Tribe´s standard Power/Toughness. If i boosted beforehand, the defending player would have just blocked with a 1/1 creature)

  • Llanowar Tribe gets tapped by decklaring it as an attacker
  • defending player declares blockers / non-blockers
  • Llanowar Tribe gets untapped and boosted +2/+2 by paying 3 (from Lands) for Umbral Mantle's Ability.
  • Then activating Llanowar Tribe `s ability to tap itself and gain 3 Mana
  • Spending those 3 Mana to activate Umbral Mantle's ability again and giving +2/+2 again
  • repeating this process infinity times.

Since the rules say:

306.4b Tapping or untapping a creature that's already been declared as an attacker or blocker doesn't remove it from combat and doesn't prevent its combat damage -

  • i thought, it was possible to go through this process after the defending Player declared blockers and before damage calculation.

Is this true or did i get that wrong?

Thanks in advance!

Looks like you got it right. Immediately after blockers are declared, players gain priority and can respond by taking instant-speed actions, which would include Llanowar Tribe and Umbral Mantle.
