To start, here's a sample list I'm assuming to be the standard.
// Mana
5 Moxen
1 Black Lotus
1 Sol Ring
1 Mana Crypt
1 Mana Vault
6 Island
1 Library of Alexandria
2 Underground Sea
4 Polluted Delta
4 Volcanic Island
// Creatures
4 Goblin Welder
1 Pentavus
1 Platinum Angel
// Spells
1 Tinker
4 Mana Drain
4 Force of Will
4 Thirst for Knowledge
3-4 Brainstorm
1 Ancestral Recall
1 Memory Jar
2 Mindslaver
1 Time Walk
2 Cunning Wish
1 Yawgmoth's Will
1 Demonic Tutor
2-3 Fire/Ice
0-1 Fact or Fiction
// Sideboard
Varies, but may include Blood Moons, Rack and Ruins, Red Elemental Blasts, Gorillia Shamans, Fact or Fiction/Skeletyal Scrying, Echoing Truth, Shattering Pulse, Hibernation, Vampiric Tutor, Coffin Purge, etc...
Any type of Null Rod aggro is hard for Slaver. Big O and FCG have such a consistant flow of threats that sometimes you can't just keep up with. Fish based decks can disrupt you enough through well timed Standstills and and gain board position through Null Rods, Wastelands and Curosities. Depending on your opening hand, sometimes you can out control these 'NullRod aggro' decks with Fire and Drains. Other hands you have to play in the combo style of the deck, just going right for the nuts from the first land drop, allowing yourself to being vunerable to disruption. And then there's the third kind of hand which comes up most often, the hand that's effected the most by their disruption. So how does one win the 'NullRod aggro' matchups?
FTK has been proven to be very effective, espically vs FCG and Fish style decks but that eats up sideboard slots that may be used for Rack and Ruins and Gorillia Shamans or even wish targets like Shattering Pulse and Echoing Truth. I'm convinced that Hibernation is the best answer to Big O and other green 'NullRod aggro' decks. Fire is the best weapon built into the MD, which is a multi-hit removal spell. So it makes sense that a multi-hit wish target would be a good idea, and the best option is given to us by
Starstom. Starstorm can be very effective once overcoming the tough early game, usually resulting in a victory. With that being said, it may not warrant inclusion over say riding the FTK's games 2+3. The biggest questions are....
1) Are 'NullRod aggro' decks worth the sideboard slots?
2) If yes, then what sideboard plan is the best way to go?
3) Or should one forget all that and say 'NullRod aggro decks are just a matchup one should take as a loss while playing Control Slaver'.
And then a 4th question comes up, looking something like...
Is the 4th Brainstorm more important to the deck to stablize it's mana base out greater than the effect of the 3ed Fire/Ice in the mirror and 'NullRod aggro' matchups?
