Why you don't upgrade sundial ?
You think that's not necessary ?
upped dials mess with the mulligan;
At the start of a match, if your opening hand does not contain any 0-cost cards, you get a new hand. this can only happen once per match.
Since upped dials have no cost to play, the chance of starting with a tower is higher if you keep them unupped.
However, why quantum towers?
Why not
towers, maybe with 1 being another SN?
Or perhaps
towers, with mark being switched to
?
