Spells without saves are always nice, though you may want to ensure that their effects are not too debilitating. Tempting as it may be to maze the party cleric the first chance you get, it would not be fun for that player to effectively sit out the entire fight in another dimension.
You have waves of exhuastion, which you can sculpt (so that is possibly the entire party starting out as exhauasted). Hit them with chained greater dispel magic, Split-rayed enervations, quickened empowered ray of enfeeblement on the fighter,
Save or suck spells include stuff like billaro's iron bands, which hold you if you fail your reflex save or entangle you even if they succeed (and I think it combos great with chain spell, even if the DC sucks for a 3rd lv spell). Though on 2nd though, there don't seem that many of them, and even fewer that are higher lv.
