If I have {mirror gallery} {vorinclex, Voice of Hunger} and a {Clone} copying Vorinclex, when do my opponents lands untap?
It will be the same as if there was only one Vorinclex. Both Vorinclex triggers will be referring to the same "next untap step" which makes the second trigger redundant.
You will, however, get a butt-load of mana when you tap a land yourself. Lol.
Still after their next upkeep- it's a triggered ability, and what happens is that when they tap a land, both abilities trigger and go on the stack, and the first resolves, the land can't untap anymore, and the second one resolves, and it just still can't untap.
Thanks just making sure
