hi Anwar, welcome to the thread. Ima try to explain myself, Candelabra is great when you have it in your opening 7 no doubt. It is fine playing it in early turns while using the excess mana to cantrip for pieces (or land) or protect spells from daze. I prefer this line of play than drawing double Candelabras early and not being able to cast a second copy because I can't protect my spells from daze or I have to cantrip for combo pieces, aside from it not being able to pitch for Force of Will. In testing, it didn't matter whether Candelabra resolved or not. But once I am able to spiral away (thanks to Turnabout), drawing extra Candelabras gets better because of the already insane mana available. However, I don't find it as efficient as Turnabouts which only require 4 to untap all lands. With Candelabra you need :1: to cast it and extra :1: for any land beyond 4, costing :5: to untap 4 lands, aside from the fact it is also non-tutorable. I have 11 untappers in my list (4 TS/4 TA/3CoT) which I believe is optimum. Mind Over Matter is powerful but too costly at 6, and needs to be compensated by Candelabras for it be more efficient than Turnabouts. It is also non-tutorable and that is why I see Mind Over Matter as deadweight in the deck without draw effects. Cunning Wish on the other hand, is there to fetch
Toils of Night and Day in my sb and untap an Island+Candelabra, jyst in case I don't draw Turnabout or Scroll post spiral. I guess that's mainly it.
