Love me some Sun Titan triggers, even if it's restricted to creatures.
Rip Apart is interesting enough, it's extremely versatile removal. It's not quite Abrupt Decay, but it competes powerwise with Feed the Swarm, I think. Hard to tell if the card is better than Wear // Tear (which has an instant speed Hull Breach mode and a Demystify mode) but it certainly kills creatures better. You pay for that with Sorcery speed and mana cost.
