The mainboard doesn't have any Land Destruction so that it could test out the deck of your opponent in the first game. If you think destroying your opponent's lands would ruin his day, bring out the sideboard and see the surprise on your opponent's face when he or she sees you destroying his or her lands. Watching the opponent doing nothing is kinda fun because he can't play any spells.
Land Destruction is very good against midrange and tri-colored decks, but bad against aggro decks(another reason why there is no Land Destruction spell in the mainboard). The mainboard is already good against midrange, but bringing out the sideboard will make the chances of winning even better.
Anger of the Gods - A spell that has great risks, because it also removes this deck's ramp creatures, Goblin Rabblemaster, Hornet queen and your tokens. A good time to use it is when your opponent has outnumbered you with tokens or ramp creatures.
Crater's Claws - A finisher or when your opponent has a creature that is big and very annoying.
Destructive Revelry - Its just 2 in the deck because the deck already has Desecration Plague and Demolish which removes enchantment or artifacts already. Use it when your opponent is enchantment or artifact oriented.
Ember Swallower - Much better when he can become monstrous very early in the game and your opponent doesn't have much permanents. Also he is a 4/5 creature for just a CMC of 4, which is quite big enough.
Goblin Rabblemaster - Perfect for the deck. It produces tokens that can be used together with Xenagos' first ability and is very dangerous when not removed immediately.
Hornet Queen - Also good with Xenagos' first ability and very good for defense.
Mistcutter Hydra - Better than Polukranos for me, because it is good against control decks and very unpredictable. Much preferred when used late game.
Windswept Heath and Bloodstained Mire - Reduces the chance of drawing a land.
Xenagos, the Reveler - Also perfect for the deck. Xenagos can cast spells or abilities very early. When using Ember Swallower's ability, better to have Xenagos on the field so that you can still produce mana even when you have sacrificed your lands.
Thanks for checking out my deck. I didn't explain other cards because they are self explanatory already. If you have any criticisms or suggestions please do so. Upvote if you like it.
