I'm building [[Casey Jones, Asphalt Hooligan]] and I'm trying to figure out how his doubling works in relation to external boosts such as equipment, auras, or +1/+1 counters.

If I have Casey equipped with say [[Tenza, Godo's Maul]], which gives him +3/+3 and trample, then activate his doubling ability, does he get +5/+0 or only +2/+0?

I would assume it'd be +5/+0, but I'm second guessing, since a friend of mine built [[Tifa Lockhart]] and said he calculates her power doubling BEFORE adding buffs from equipments, auras, and such.

Pretty basic question, honestly. When I swing with \[\[Cecily, Haunted Mage\]\], both her ability and \[\[Doom's Time Platform\]\] trigger. Can I suspend the spell I cast that turn with Cecily immediately, or does it have to be in the graveyard already on the attack trigger?

I've been building decks along the color challenge (making at least one deck per color combination) and for Golgari, I'm really interested in running [[Sarevok, Deathbringer]] and [[Raised By Giants]] as the commander and background.

I've tried building it sacrifice heavy with the reasoning of "if they don't have anything to remove, they can't have anything leave the battlefield." While this seems to kinda work, it gets hard countered by any treasure, token, sacrifice deck, or anything similar because they either make enough in one turn to sacrifice anyway or can just get something killed in combat. Not to mention fetch lands exist, which is a whole other issue.

Are there any cards I can throw in to mitigate these hard counters, or even a completely different archetype to build for Sarevok that prevents being hard countered by 30% of Magic decks?

Pretty self explanatory honestly. The only "synergy" I can find are voodoo spells spawning candles on fire puddles just like they do any other puddles. For Acid and Elec, this is usually enough because they both make SO many puddles, but the Pyro spells that leave puddles are either Fireball or Finger Guns, which are both kinda meh, and Firebeam which has me waiting until the beam is gone which is a bit tedious.

Are there any other synergies between Voodoo and Pyro? On a similar note, are their synergies between Voodoo and either Elec or Acid? I know Voodoo goes really well with Cactus in several ways, but I already have that fully leveled up and want to level up the rest of the magics.
