As for debuff, Nerf itself should be the best choice for anyone. Even better than weaken combination or anything else. At least that's how I play it.
Let's confine the discussion to mages, on single legend rounds for EODs in normal difficulty.
You have a range of spells to choose from:
Buff spells: regen2, haste, SV, spark, aranca focus, spirit shield.
Debuff spells: poison, slow, weaken, bewilder, blind, silence, nerf
We need to establish a few principles:
1. We need a spell which can effectively prevent us from dying.
2. We need spells which can buff our damage.
3. We need spells which can replenish our health.
4. We need spells which can improve our stat.
5. Buffs are better than debuffs, assuming they serve the same purpose.
Unless you need to fight 50 or more turns per round, you're bound to waste some mana on those debuffs, since they cannot be brought to next round.
Those wasted mana will accumulate to some noticeable amount, since you need to repeat the whole process 50 times.
So...
1. Spirit shield is a no-brainer. Way too better than spark and silence.
2. Aranca focus is a must. Nerf and bewilder in the waiting list.
3. Regen2.
4. Haste, SV.
Up till here, we have established what buff spells to use.
5. The argument here is: let spirit shield and regen2 do its work.
Without any debuffs, legends are hitting me with 400-500 damages. Since I have about 30% evade, it means legends are hitting me with less than 300 damages per round on average.
This amount of damage should easily be covered by regen2 (even lv.220 player with 110 prof. should be able to replenish least 270 hp per turn. Yes, I calculated that)
(If you feel uncomfortable, use oak staff of heimdall. It surely helps)
Thus you don't need to further decrease the amount of damage you receive. Which means you don't need poison, slow, weaken, blind.
Bewilder and nerf's a bit different. Since they decrease legends' defense, they pretty much act as a buff to our damage.
I haven't tested bewilder, but I should save 2 banish per round with nerf on right now. Minus the cost to cast nerf, it means I can save 1 banish per round. And again, for 50 rounds it will accumulate to a large amount of mp.
In short, with regen2/SP shield/aranca focus/SV/haste/nerf, you should be able to clear EOD in a mana-efficient way.
Anyone feel free to discuss if I have made any incorrect assumptions, or you have different opinions.
