Magic is all about card advantage – getting your money’s worth out of a card, if you will. The classic card advantage featured value of 3 of an effect for 1 mana – lightning bolt (3 dmg for 1 red mana), ancestral recall (3 cards for 1 blue mana), etc – but that was when things were broken. Now you’re lucky to get 2 of anything for 1 mana – shock, preordain, etc. (ponder is close but the lack of full manipulation gives you the third card in exchange).
Generally, good players cling to cards that give you a high ratio of effect-per-mana spent. For example, Midnight Haunting, Divination, and Brimstone Volley (without morbid) all give you 2 of their effects for 3 mana, and those have been playable cards in the standard formats of present and past. Considering that, imagine how good it would be to get 7 of a spell’s effect for only 3 mana! That is what Stomping Slabs does.
Stomping Slabs gives you the opportunity to throw SEVEN to your opponent’s face, for only three little mana! It also gives your opponents stress ulcers as they watch their fate unravel in your hands as you turn over those 7 cards. Will they be taking 7? Only the Slabs knows. And considering the modern format including fetch lands, you can filter out some mountains to make it more likely to hit another slabs! Turn 1 Rift Bolt suspend, turn 2 double lightning bolt and rift bolt resolving all to the face for 9 damage, turn 3 stomping slabs for 7. You’re only a flame javelin away from a turn 4 win. Can’t beat that!
Those who fear not hitting another slabs need only consider the odds. In a 60 card deck, you have 53 cards left once you take your opening hand. Worst case scenario you’re on the play with 51 cards left when you play that slabs on turn 3 for a 3 in 51 or about a 6% chance the first card revealed is another slabs, and 6-7% odds subsequently for the other six you turn over (I’m not good at math, but that’s like a 42% chance to get it right?). With odds like that, how can you not play Stomping Slabs…it’s an automatic four-of in any red deck!
Stomping Slabs is even more insane in a draft deck….First pick in a Lorwyn-Morningtide-Morningtide draft all day! You only need 2 to make it happen, and with only 40 cards in a deck you’re even more likely to hit a second slabs on the reveal than in a constructed format!
