The first one was: Inky, vamp, rit, lotus, swamp (after double mull). Pretty much a lost cause, but I think the line I might take is a hail mary to vamp for bargain, cast it turn 2 off rit and lotus. Most likely lose, but if I can stick it I might be able to put up some struggle. What approaches might you take?
You're probably not going to do much better with a mull to 4. Turn 2 Bargain (or Necro if your opponent plays a Sphere, or if they are showing Spell Pierce) is perfectly acceptable.
The second, much more interesting one was: Sea, Ponder, Duress, Delta, Demonic, Mystical, Yawg's will. Obviously a keeper. Feels a bit limited on fast mana, but the strong closers make it worthwhile. Duress, and then maybe depending on the draw, myst/ponder into recall? The hand feels way too open ennded to goldfish, but what hypotheticals might make you go one way or another with it?
This is a 2nd turn kill.
T1 - Sea, Duress
T2 - upkeep Mystical for Dark Ritual
draw Rit
Delta -> Swamp, Rit, Demonic Tutor for Black Lotus, play Black Lotus, cast Will with B floating, recast Rit, replay Lotus, sac Lotus for UUU, play M.Tutor for Tendrils, Ponder into Tendrils, cast Tendrils for 20 life.
One last hand: Swamp, duress, cabal rit, yawg's will, recall, brainstorm, FoW. Very tempting, and drawing just one island or a dual means a lot of fun, but if you whiff on mana it's likely to fold. I'm leaning toward a mull here. When would you keep this hand, if ever?
In most instances I would mull this. I would keep this if I knew my opponent's deck was fragile and that Duress/Force would stop them cold (like Belcher) but I would def mull this in any reasonable match.
