Petr Brozek's Kuldotha Red
Creatures
4 Memnite
4 Signal Pest
4 Ornithopter
4 Goblin Bushwacker
Spells
3 Mox Opal
4 Kuldotha Rebirth
4 Flayer Husk
4 Galvanic Blast
2 Lightning Bolt
4 Devastating Summons
4 Chimeric Mass
Lands
15 Mountain
4 Contested War Zone
With that there's not a lot in this list that needs to be altered for post rotation purposes, the landbase is just fine as it is, 19 lands with 15 basics and 4 contested war zone is perfect for the deck to replace the cards we're gonna look at, let's take a look at potential choices for the deck itself.
Shock - The new replacement for Lightning Bolt, will easily fit into the 2 of slot, probably gonna end up bumping it to 3 maybe if there is room.
Crush - Believe it or not this one red drop spell is pretty awesome in itself, deals with opals, bombs etc takes out a whole slew of heavy artifact things, including ramp cards like Sphere of the Suns
Panic Spellbomb - Yes another great target for kuldotha red in this case, if your going artifact heavy this is your choice of card for the deck, plus you can use it's secondary ability when it goes boom from rebirth.
With that in mind let's look at the spells now
Spells
4 Flayer Husk
3 Mox Opal
4 Kuldotha Rebirth
4 Galvanic Blast
2 Shock
4 Panic Spellbomb
4 Chimeric Mass
Creatures wise we are gonna have to replace the goblin guide and bushwacker with something a bit more impressive let's look at some better dudes for the deck.
Phyrexian Revoker - Yep, something that deals with walkers, ratchet bombs, the works basically, perfect rebirth target too, probably put him as a 3 of in the deck or 4 of, depending on what he's needed for.
Goblin Wardriver - Why isn't this in the list, this is the best dude in red and double red is nothing to scoff at, seriously this guy is the best red dude ever printed, 2/2 for a 2 red mana dude with battle cry, busted fun.
Goblin Chieftain - I guess since he's back in M12 i guess this makes him a valued choice for this deck since it makes tons of goblins, +1/+1 and haste is also nothing to scoff at for 3 mana as a 2/2 period powering the extra few points of damage so well.
So here is the creatures for the deck let's take a look
Creatures
4 Memnite
4 Signal Pest
