Here's the thing, Thresh actually has a significantly slower clock than this deck. Whereas Thresh doesn't even have creatures big enough to attack with till around Turn 3-4, and very few at that bc it spent most of that time playing cantrips, and even then creatures like Meddling Mage that you wouldn't want to attack with period if there's even one 2/1 on the field. By the time Thresh starts attacking, this deck can easily bring your opponent down to half their life.

If anything, Daze is relevant a good big larger percentage of this deck's average game than in Thresh. So why are you guys worry about how good it is in the late game. There shouldn't even be a late game and usually isn't if you're running FoW and Daze to protect your early threats.

Being able to protect your turn 2 Crystalline even without FoW is huge. Being able to protect your muscle sliver early on when you don't have a crystalline of FoW is huge. Just making your opponent wait an extra turn to do everything, to have a one sided Sphere of Resistence is huge. Daze in general makes sure your opponents life total falls very quickly.

I think the real debate is between Stifle and Counterspell. And I do think Counterspell wins that debate just because of it's increased versatitliy.

In most matchups, the only good Stifle targets are Fetchlands, which in the lategame is worse than Daze IMO. And in some matchups there aren't even many if any fetchlands to hit. Yes Stifle is gold against goblins, but I can't fathom why goblins would be such a hard matchup for you guys, seeing as how I do fine against it with Thresh running a lot fewer threats, and threats that are useless for anythng but trading with lackey for the first many turns, and threats that are generally smaller than these slivers are by turn 3-4.
