Sulfuric Vortex is your man. This nifty permanent will do upwards of 20-30 total damage per game by itself and solves your lifegain issue. Success!
Also, try to chain your burn cards for 10-20 damage bursts to each opponent. Doing so will give Oloro or whomever less time to buff their life totals back up. E.g. guttersnipe > flame rift, swing, post-combat earthquake.
