Animi cards will all be Other creatures with the same cost, same base stats (before elemental bonuses), and an effect that supports the inclusion of creatures of that element that is triggered by the same condition of "1 turn after you summon or generate this Animus"
I don't see how this could be better than ancestral recall since it costs quite a lot (you can't just draw and play it like nova), the effect can be countered, it isn't an instant, and there is a hand limit that you must always adhere to, including during the beginning of your turn, which is the time that the effect activates, when you have already lost hand space drawing.
