Welcome, this deck is designed for the casual "Horde" format. The list below includes quick references for everything you'll need to know how to play.

To clarify Some things, tappedout doesn't have a way to main board tokens, so metallic sliver takes its place. In the physical deck it would be 20 Sliver tokens.

What is the Horde format?

Horde is a casual format where a pod of players team up against an autopiloted boss deck, à la Archenemy. The teammates also share lifetotals, akin to Two-Headed Giant.

Best way to pick this up and play?

If you find that this Horde build is outside of your budget; this is a casual format, so running proxies, or even going to the playtest section of this deck are both valid ways to play.

Click on each section below to expand it to learn more.

What You'll Need to Play

At least one Magic The Gathering deck, the Sliver Horde deck, and a coin (Or a die of your choice). It is recommended that you carry additional items; of your choosing, for keeping track of counters and tokens on the battlefield / life totals.

Beginning the Game

Players versus the Horde are on a Team. A team takes their turn together, meaning they go through all phases of the turn as a team. The Team begins the game with a shared life total of 30. Teams do not share any resources other than life--meaning players can't share cards in hand, or mana. The Team always has first turn.

The Horde's starting life total is 45, plus 5 for each additional player beyond 1.

Combat Phase

Any time a player would deal combat damage to the Horde, that player may choose to redirect the damage to the Hive. Doing so nullifies the damage, however it triggers the Horde's alternate Upkeep effect. (See section "Piloting the Horde": "UPKEEP" for more details.)

If the Horde is attacked; it cannot normally assign blockers, and will take the assigned damage.

Piloting the Horde

UPKEEP

(Counters on the Hive cannot be interacted with, except by the Horde's effects. Effects like Proliferate, or cards like Solemnity have no effect on the Hive.)

If the Hive has any Time counters on it, remove 1 Time counter. Flip a coin, or roll a die, and apply one of these effects based on the result. If the Hive received combat damage since the Horde's previous end step, subtract the result from the total instead.

• Heads/Even: Add 2 Cast counters to the Hive.
• Tails/Odd: Add 1 Cast counter to the Hive.

Next, reveal the top card of the Horde's library and cast the spell. Repeat this step times, where ‘’ is equal to the number of Cast counters on the Hive.

COMBAT PHASE

• All creatures the Horde Controls will attack if able. The Horde will target Planeswalkers before the Team with both effect, and Combat Damage.

• The Horde cannot activate Mana effects / abilities.

• The Horde cannot activate effects / abilities that say, “may".
• The Horde will always pay the costs of all forms for triggered abilities, or if the Horde is given a decision to pay a cost (Some examples include Rhystic Study, or Sphere of Safety, their costs will always be paid).

END STEP

• If the Hive has no counters on it: Cast The First Sliver from the command zone. Then place Time counters on the Hive, where ‘’ is equal to the number of times The First Sliver has been cast from the command zone this game.

If The First Sliver is removed from the battlefield, return it to the command zone (This includes when returning it to hand).

Winning / Losing

The Team wins:

• When the Horde's life total reaches zero.

• When the Horde's battlefield is empty of creatures, and it attempts to pay the upkeep cost with no cards in its library (at the same time).

• An alternate win condition is met. (E.G. Poison Counters.)

The Team loses:

• When the Horde reduces the Team's Life to zero
• When a Teammate would attempt to draw a card with no cards in their library.

In Depth Breakdown For Questions You May Have

• The Horde has no Draw Step, or Main phases.

• The Horde enters the End Phase after it conducts its Combat Phase.

• Spells and effects that target players can target the Horde as if it were a player. Combat Damage can be redirected to the Hive.

• When spells are revealed from the top of the Horde’s library for the upkeep cost, they are cast from the top of the deck, and never interact with the Horde’s hand.

• When revealing a card from the top of the Horde's library to be cast, cast the spell and resolve it before revealing the next card.

• If a card(s) were placed in the Horde’s hand, they are cast during the Upkeep, regardless of spell speed.

• The Horde can gain life, and have permanents placed in any legal zone as if it were a player.

• Milling the Horde out, or decking it out will not kill the Horde. An empty Library, and zero creatures on the board will result in a loss for the Horde if those conditions are met during its attempt to pay for the upkeep cost.

• The Horde will always have the correct amount of mana, color, and type of mana in its mana pool to cast spells, or pay costs (If the Horde is not casting a spell, or paying a cost, treat it as if it contains no mana in the mana pool). Cards and their effects cannot change the amount, color, or type of mana the Horde produces.

• Token creatures cast from the Horde’s library behave like normal cards. Token creatures cast this way are subject to all possible elements non-token creatures are subject to. (E.G. remaining in the Hand, Graveyard, or Exile.)

• Tokens that entered the battlefield via a spell effect (E.G. Hive Stirrings) are treated as normal tokens, and cannot perform actions such as remaining in the Hand, Graveyard, or Exile.

• Any decision made by the Horde is done so as randomly as possible. There are select instances where decisions are dictated. (E.G. A decision that is not dictated would be spells that "Tempt" the Horde, like Tempt with Discovery.)

Dictated Decisions by the Horde

The First Sliver

The First Sliver is cast only when fulfilling the Endstep requirements. If The First Sliver would be removed from the Battlefield, return it to the Command Zone.

Patriarch's Bidding

• The Horde will always choose “Sliver” for the creature type.

lurking predator’s effect

• If the revealed card is a non-creature spell, the Horde will choose to place the card on the bottom of the library.

Thank you for taking an interest in my Sliver Horde deck. Boss decks like these are a great way to get friends together to fight a common enemy. If you feel there are issues with balancing, or that the deck seems too difficult / easy, please let me know, and how you feel that could be adjusted in the comments below.

Thank you, and remember to have fun out there!
