Honestly, this app is no-frills and rather rudimentary in nature, but it also comes with a few other handy features for enhancing your MTG gameplay experience, including poison counters, a dice roller, a game over detector, and more
And you can run evoke in reanimation decks that can evoke for three and then recur with something like Karmic Guide
The affected land will remain a creature until the end of the game, it leaves the battlefield, or some other effect changes its card types, whichever comes first
Once the planeswalker lands, you might cast more colorless spells to add more removal, but its plenty good to just kill a threat so Ugin sits around drawing cards
If you can cast him in the same turn that he is removed, you'll get maximum return from his token spawning ability
