Horde's Thunder is a 
archetype ramp deck.
More lands mean bigger creatures to smash your enemies with.
Step 1: Find more Lands[]
Look for cards that let you get more lands onto the battlefield than the normal one-per-turn.
Choose 8 cards.
Step 2: Big Creatures[]
With your abundance of mana, you can play bigger creatures much earlier in the game than your opponent can. Choose some real bruisers!
Choose 6 cards.
Step 3: Fill your Deck![]
You need a few more cards to complete your deck:
• Creatures are important! Most decks want to include 20-30 creatures.
• Variety is good. You want creatures with lower mana cost to cast early, but also include a few high-cost powerhouses to finish off your opponent.
• Removal is key. Select cards which remove your opponent's best threats and victory won't be far behind.
Choose 22 cards.
Step 4: Lands![]
The right mix of lands helps make sure you'll be able to cast all your spells. The recommended number and type of lands have been automatically added to your deck.
24 land cards are added.
Step 5: Customize your Deck![]
Choose an avatar with background art, card sleeves and name to represent your deck!
