Temur Breach by RatsRelyk – Theros Beyond Death Standard Theorycraft
Here is a spicy deck for you: Temur Breach! The name of the deck showcases the powerful combo-kill card Underworld Breach. This deck works to stall the early game using the powerful Uro, Titan of Nature’s Wrath. Uro ramps us along with Growth Spiral to get to our important 5-drops, Cavalier of Thorns and Escape to the Wilds. These cards further ramp us to drop land after land building our Underworld Breach.
Brazen Borrower and Negate help to slow down opponent interaction to allow us a large late game turn. Early removal in Shock and Scorching Dragonfire work to stop aggressive decks or take the last loyalty off of a planeswalker.
Our big turns revolve around Breach casting Shock over and over again to finish off the opponent. If we need more than one Breach the first one can be used to generate more value with cards like Uro (escape paid cheaply!) and Stern Dismissal (bounce all those creatures!).
This deck is built with Bo1 in mind but can easily be adapted for Bo3. I would add more counterspells (especially Mystical Dispute and Whirlwind Denial), 3x Return to Nature, 2x Flame Sweep, 2x Narset Parter of Veils and 1 Ugin, the Ineffable.
