Really? I haven't sleeved up Bant Drazi in a long time but Affinity and Burn never really used to give me trouble. Decks like Dredge, Storm, and Tron are the problem matchups
Nope, spell Queller can't target the same spell when it's blinked because the blink resolves all at once. Spell Queller ETBs before the other player can even cast the previously exiled spell.
Also, I don't think Knightfall ever really boards out Queller. Even though it misses Smasher, Drowner, etc. and can be flickered by Displacer, it's still one of the most powerful cards in the deck
Yeah I ran this list a few times.

It's a lot of fun. Evolution is a blast to play with but of course sometimes it really sucks too
