commander · Riku of Two Reflections
Mirror Mastery (CMD).
A Temur copy and double deck from the original Commander set, led by Riku of Two Reflections — pay two mana to copy any instant or sorcery, or pay three mana to copy any creature entering the battlefield.
The Commander
Mirror Mastery is one of the original 2011 Commander precons and Riku has one of the broadest doubling effects in the format. Whenever you cast an instant or sorcery, pay two mana to copy it. Whenever another nontoken creature you control enters the battlefield, pay three mana to create a token copy of it. Every spell doubles, every creature entry doubles. A single Riku activation on a Tooth and Nail resolves two Tooth and Nails simultaneously. An Avenger of Zendikar entering creates a token copy of Avenger, instantly generating twice the Plants.
Riku of Two Reflections rewards impactful enter-the-battlefield creatures and powerful instants and sorceries. The deck runs Animar as an alternate commander for a +1/+1 counter-based strategy, Edric for card draw rewards on combat damage, and Intet for top-of-library manipulation. The primary Riku strategy is explosive turns where doubling spells and creatures generates more value than opponents can respond to.
Key Cards
Animar, Soul of Elements
Gets a +1/+1 counter whenever you cast a creature spell. Has protection from white and black. Creature spells cost one less for each counter on Animar. An alternate commander in the deck that enables an entirely different strategy — build Animar's counter count by chaining creature spells, then cast massive creatures for zero mana once Animar has eight or more counters. With Riku copying creature entries, each doubled creature entry also adds a counter to Animar in addition to the doubled ETB value.
Edric, Spymaster of Trest
Whenever a creature deals combat damage to a player, its controller may draw a card. Every creature dealing damage to opponents draws a card — including opponents' creatures attacking each other. With Riku copying creature entries, each copy of Edric creates two identical triggers. Two Edrics means drawing two cards for each creature that deals combat damage. The deck naturally runs enough evasive creatures to connect reliably, converting combat damage into massive card draw.
Intet, the Dreamer
Whenever Intet deals combat damage to a player, pay two mana to exile the top card of your library face down. You may play that card for free until end of turn. Consistent combat damage with Intet chains free spell casts. In a Riku deck, if that exiled card is an instant or sorcery, paying Riku's two-mana copy trigger doubles it for four total mana. Free spells, doubled. If the exiled card is a creature, Riku's three-mana copy trigger doubles the entry. Intet generates the free casts that Riku doubles for maximum value.
Magmatic Force
At the beginning of each upkeep, Magmatic Force deals three damage to any target. Every upkeep — yours and each opponent's — it fires. In a four-player game, Magmatic Force deals twelve damage per turn cycle without any other input. With Riku creating a token copy, two Magmatic Forces deal twenty-four damage per turn cycle. Combined with Edric's card draw from combat damage, the deck generates twelve to twenty-four free damage and draws per turn across the table.
Simic Sky Swallower
A 6/6 flying trample shroud creature. Riku copies it on entry — two 6/6 flying tramplers with shroud for seven mana. Neither can be targeted by removal. Two unblockable-in-practice 6/6 tramplers in the air deal twelve damage per swing to any two players, and shroud means opponents need board wipes to answer them. This is the deck's simplest non-combo win condition: Riku copies Simic Sky Swallower, attack with two uncounterable 6/6 flyers.
How to Play
Get Riku onto the battlefield by turn four or five and keep mana open to activate his copy triggers. The ideal early play is Edric alongside Riku — evasive creatures dealing damage to opponents generates two cards per hit with two Edrics in play, fueling the hand for bigger spell turns. Mid-game, use Riku's spell copy on your best draw or tutor effect, doubling card access. The explosive winning turn: cast a game-ending spell like Tooth and Nail, pay two mana to copy it with Riku, resolve both simultaneously. Or enter a creature like Avenger of Zendikar, copy it for three mana, and field twenty-plus Plant tokens immediately. Magmatic Force copies from Riku deal twenty-four damage per turn cycle while you assemble the final blow.
