65/100
Gains value in 2HG: symmetrical lock piece, cheap interaction.
Stax and tax effects tax two opponents for the price of one, while your team plans around them together.
Turns are shared and fast in 2HG. One- and two-mana answers let you hold up interaction without losing tempo.
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.
Split second (As long as this spell is on the stack, players can't cast spells or activate abilities that aren't mana abilities.) Counter target activated or triggered ability. If a permanent's ability is countered this way, activated abilities of that permanent can't be activated this turn. (Mana abilities can't be targeted.)
Shares the "symmetrical lock piece" 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 Trickbind.
