[ability]Sear Magic[/ability] will remove [ability]Minefield[/ability], [ability]Death and Decay[/ability], and [ability]Cyclone[/ability] from the battlefield!
[ability]Focus[/ability] will allow your attacks to hit through [ability]Blinding Poison[/ability]. [ability]Laser[/ability] will as well.
[ability]Wild Magic[/ability] will allow DoT/Multi-hit abilities to deal dmg through [ability]Sandstorm[/ability] / [ability]Shell Shield[/ability]. So will [ability]Black Claw[/ability],[ability]Foreboding Curse[/ability], and [ability]Exposed Wounds[/ability].
[ability]Arcane Storm[/ability] will keep self-stunning moves from applying the stun (i.e. [ability]Ghostly Bite[/ability]).
Abilities like [ability]Ice Barrier[/ability] can be used strategically to the other person's advantage as it blocks two attacks from EITHER team. Basically, I never attack when Ice Barrier is cast by the other player, and either swap to get ready, or heal/defensive prep. This is also very useful as many people who use [pet]Mr. Bigglesworth[/pet] will cast ice Tomb before using the barrier, and if you don't attack, the tomb may be blocked by the barrier!
Abilities like [ability]Surge[/ability] are great against stun-if-user-goes-first types of moves, such as [ability]Horn Attack[/ability] and [ability]Kick[/ability]. If you use the ability and go first, you will avoid the stun.
HoT abilities like [ability]Soothe[/ability] and [ability]Renewing Mists[/ability] can stack, making for some excellent regen.
A few pets can get three ticks of regen from [ability]Plagued Blood[/ability], even without a multi-hit main attack. [pet]Fel Flame[/pet] can do so with [ability]Immolation[/ability], [ability]Scorched Earth[/ability], and [ability]Flame Breath[/ability] (technically he can have four ticks of regen if you include the initial dmg from FB). [pet]Scourged Whelpling[/pet] can do so with [ability]Death and Decay[/ability], plus [ability]Tail Sweep[/ability] if it hits twice (go for the h/h/ breed here). Of course, the potential king of this would be the [ability]Clockwork Gnome[/ability] using [ability]Build Turret[/ability] and [ability]Blitz[/ability].
A few mutli-hit abilities will get a few hits in through [ability]Blinding Poison[/ability], even without hit modifiers. Abilities like [ability]Build Turret[/ability], and [ability]Blessed Hammer[/ability] are a few examples.
All right, let's see some creativity at work!
