Battle — Siege // EnchantmentMarch of the Machine
52/100
Mixed in 2HG — protects a teammate, but duel-shaped card.
'Target player' and 'target permanent' effects can be aimed at your teammate — you can't do that in a duel.
Cards that reference 'the opponent' or single-combat framing lose reach when the table has two opponents.
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.
Invasion of Gobakhan
(As a Siege enters, choose an opponent to protect it. You and others can attack it. When it's defeated, exile it, then cast it transformed.)
When this Siege enters, look at target opponent's hand. You may exile a nonland card from it. For as long as that card remains exiled, its owner may play it. A spell cast this way costs 
more to cast.
