The previous incarnation of this deck focused solely on things that blew up lands which is the point, but it seemed to have a tough time keeping itself afloat in battle. I'd end up behind, or outnumbered, or out of cards and out of options. This new version should be much scarier! Fear it!
4 x Llanowar Elves - For the cheap ramp.
4 x Akki Blizzard Herder - For the cheap land destruction.
1 x Krosan Restorer - Helps get lands back.
1 x Dwarven Driller - Helps destroy even more lands!
2 x Countryside Crusher - Gets stronger and stronger.
2 x Terravore - Hey! I get stronger and stronger too!
1 x Mina and Denn, Wildborn - For the additional land play and trample.
4 x Winter Orb - Brrr, it sure is getting cold. ;) Slows things right down.
4 x Custody Battle - Just hand those creatures over.
3 x Crown of the Ages - And... now hand another creature over.
3 x Gruul Cluestone - More ramp.
3 x Harrow - Some more awesome ramp!
3 x Roiling Terrain - Bam! Damage! Ow!
1 x Price of Glory - Don't even think about using instants during my turn.
12 x Mountains
11 x Forests
First off, the biggest difference in this deck is now the inclusion of 4 Winter Orb's and the addition of ways for me to ramp despite my land situation. Winter's Orb slows the game to a screeching halt... if you don't have alternative ways of creating mana. The cluestone and elves help ramp it up and the fact that 90% of my deck can be cast with 3 or less mana definitely helps. I really wanted another one or two Krosan Restorers because once threshold is reached, and it will be with this deck, it can produce so much mana. Unfortunately, I only have one and everywhere I looked was out of stock.
Secondly, the deck now includes some Crown of the Ages to accompany the already present Custody Battles. They go together like peanut butter and jam and bread and it's oh so delicious. Opponents will either have to lose a land, or risk permanently losing a creature to my side. Crown of the Ages can move Custody Battle to other creatures, and the original creature would remain under my control. It's devious and deadly.
Third. I've got some potentially heavy hitters in the deck now. Previously I had next to nothing for this job and at some point you got to hit back. Terravore and Countryside Crusher are perfect for this deck. They should be big and bad in no time.
Finally, I've added a few other cards that could prove useful. Mina and Denn, Wildborn will let me play additional lands and give those heavy hitters some trample. Harrow will help me ramp. Price of Glory will protect and potentially destroy even more land. I do love Price of Glory.
All in all I believe it's a large improvement over the original incarnation. Terra Terror should be interesting to say the least!
