1. 1-4. I always Revoker naming Mangara. On the play I play Dynamo+Revoker. You're forced to play Karakas and represent mana tithe for Ugin, which I run into T2. T2 you play mangara, T3 I digger Ugin back and hold dynamo up. T3 you blow up revoker with pridemage, but you need to use an untap to both play+sac pridemage and hold up karakas. So Mangara either exiles one of my things and recurs, in which case I recur revoker with the other mana source and force the draw, or it eats two things without going back to hand and we draw. On the draw I'm too slow and you get to Mangara nonsense me out.
3. 3-3. On the play I T1 revoker, which you have to counter, and digger. Next turn I digger+replay revoker and eventually get the Ugin out. On the draw you play out mangara, counter my Revoker, blow up my land and win with the goblin. (Also Chancellor of the Forge+Foil+Island is a nice general 5CH shell.)
4. 3-3. On the play I revoker you out of the game, on the draw you play two threats Ugin can't deal with (memnarch is unfortunately colorless, whomp whomp). Archetype is a great idea btw.
5. 0-6. Revoker stops me cold, while confluence deals with my own revoker.
