Quote from astebel »Hi everyone. I have searched for the rules to this interaction and found conflicting answers.
Plains with a Genju of the Fields attached. If I have a pump spell to play like Mutagenic Growth can I play it in a way to take advantage of the multiple activations of Genju to gain even more life?
Example: Activate Genju x3 (6 paid mana) then play MG and deal 4 damage. Do I collect 12 life? As Genju is a 4/7 for each instance.
Correct each activation of the animation ability grants an instance of the triggered ability. Each one will fire when it deals damage. In Your scenario you would get 12 life
Does the order of the activation of MG and the Genju activations matter?
Example: Activate Genju (pay 2), then activate MG, then activate Genju 2 more times (pay 4 mana). Then do damage. How much damage is dealt and life gained?
The order you activate the abilites cast the spells does not matter as they are applied in different layers. Any ability that sets the P/T of of a creature is always applied before any ability/spell that modifies it like mutagenic vault.
Regardless of the order you cast the spells/activate the abilities the genju will end up as a 4/7 and you will get 16 life.
