I managed to 4-0 our prerelease with this:
Used sideboard cards were
Negate,
Naturalize and
Fog.
The mana worked out perfectly and my splashed removal could alway be cast on time. The four spiders did a ton of work and allowed me to cast the whale in a lot of games.
Scavenging Ooze was absurd everytime it got cast.
Time Ebb was often very brutal because it could punish land light draws from my opponents very early in the game.
My favorite moment was when I got to cast
Colossal Whale on turn 6, then follow it up with
Clone on turn 7. It's pretty hard to lose when you got the whaleadvantage
.
Ogre Battledriver was a very scary card to sit accross, especially in combination with
Young Pyromancer.
Overall I enjoyed playing the format quite a bit. The cards felt refreshingly simple after playing with MMA and DGR.
