Did you miss the Delvers? I’m not a control deck.

recall is good if you’re racing affinity (like merfolk does). in control, bouncing everything is not helping that much. I rarely have the feeling recall is breaking me. vandalblast breaks me.

Indeed, racing with etched champion goes faster with signal pest, master of etherium, cranial plating and/or arcbound ravager, but if you’re wasting all sources to answer these cards, I have time for the slow race. You can’t put much danger in play if you spend resources on holding off the other cards.
Don’t forget you’re taking much damage yourself from land + early race from affinity.

Don’t forget we have sideboard too ;). currently I play 4 spell pierce after side.

I’ve been toying with the idea of cutting Delver, and if I did that I’d run Tar Pit. Coming into play tapped is VERY bad for this deck, though Tar Pit is great in controlling versions of Grixis.

The deck plays plenty of threats, and has a great burn plan. I’ve even been boarding Delver out against matchups like Burn, and it’s not a problem. I believe that you’re underestimating the value that Kolaghan’s Command adds in the threat department. It’s also very Relevant that only a handful of removal spells can kill Tasigur in the first place.

I played a sideboard Hurkyl’s Recall when I played Izzet (with and without T. Cruise) and played better than Vandalblast and also played better with Snapcaster Mage. It was only a one-of for that one matchup, and even when I didn’t draw it the matchup felt positive. I figured since Kolaghan’s Command is so great against Affinity that I don’t need the Recall anymore.

Champion, even when enabled, sucks if you don’t have a plating or Ravager to go with it. With Spell Snares and Snapcasters, it’s not hard to keep that on lock.

I should kill him before turn 5, but the other removal spells made that difficult. And it’s his only answer against my etched champion.

So if you want to win against affinity, I would play that card in SB for sure.
