Legendary Planeswalker — TeferiInnistrad: Midnight Hunt
67/100
Mixed in 2HG — hits each opponent, but incremental lifegain.
There are two opponents in 2HG, so every 'each opponent' clause resolves twice against a single shared life total.
60 shared life is a bigger pool than 20, so small lifegain is proportionally weaker — and it's the same pool your teammate is spending.
Ratings start at a neutral 50 and are adjusted by rules derived from 2HG's structure — shared 60 life, shared turns, two opponents. They'll be recalibrated against real play rates once teams start submitting decklists.
+1: Choose up to one target artifact, up to one target creature, and up to one target land. Untap the chosen permanents you control. Tap the chosen permanents you don't control. You gain 2 life. −2: Look at the top three cards of your library. Put one of them into your hand and the rest on the bottom of your library in any order. −7: You get an emblem with "Untap all permanents you control during each opponent's untap step" and "You draw a card during each opponent's draw step."
Shares the "hits each opponent" axis — good candidates for your teammate's deck.
Suggestions are characteristic-based for now. Once teams submit pairings, this becomes a real co-occurrence score: played in X% of teams whose partner deck runs Teferi, Who Slows the Sunset.
