I’ve been thinking about building a Slicer, Hired Muscle commander deck where I load it up with equipment/auras and have it reap the “on attack/combat” benefits multiple times a turn cycle. The only problem: is this how it actually works?
I know that if, for example, an equipment you control grants hexproof to an opponent’s creature, you still can’t target it since the creature has the keyword and you don’t control the creature (explained here). But is the general rule, therefore, that if an equipment/aura controlled by you grants a keyword or ability (i.e. “creature gains/has ‘X’”), it benefits the opponent, whereas if it doesn’t grant the keyword or ability it benefits you?
As an example, take Diamond Pickaxe. It has:
Equipped creature gets +1/+1 and has “Whenever this creature attacks, create a Treasure token.”
So when an opponent attacks with my Slicer equipped with Diamond Pickaxe, who creates the treasure token? I assume the opponent, in this case, since the treasure creation is an ability given to the creature, which my opponent controls. On the other hand, I assume that if Slicer was instead equipped with a Bitterthorn, Nissa’s Animus, which says, in part:
Whenever equipped creature attacks, you may search your library for a basic land card, put it onto the battlefield tapped, then shuffle.
then when Slicer attacks on my opponent’s turn, it’s still me that gets to search for a land, since the ability is on the equipment, which I control. Have I got the right understanding in both cases, and in either case, where is this addressed in the rules?
