Rainbow Depths is among the fastest and most straightforward versions of a [[Dark Depths]] deck by dedicating most of the deck to assembling the combo and protecting it. This makes executing the combo brutally effective, but there is no alternative game plan. The Rainbow part of Rainbow Depths is because the mana base is cards like [[Gemstone Mine]], [[Mana Confluence]], and [[City of Brass]]. The deck is so quick that the loss of life doesn’t matter too much and they just want to always have access to all of their colors of mana. A common strategy to fight Dark Depths has been to bring in [[Submerge]], but when there aren’t any [[Forest]]s in the deck then that becomes less effective.
How does Rainbow Depths matchup against TES?
[[Vampire Hexmage]], [[Dark Depths]], [[Thespian’s Stage]] – These three cards is what the entire deck is based around. Both [[Thespian’s Stage]] and [[Vampire Hexmage]] remove the counters from [[Dark Depths]] to create the [[Marit Lage Token]]. Because two of their three combo pieces are lands it can be tricky for us to interact. We can only interact with the token it makes. Their combo is pretty fast because it doesn’t take much mana to execute, but it does require an attack stop and [[Marit Lage Token]] doesn’t have haste, so we get an extra turn after they assemble their combo
[[Crop Rotation]], [[Sylvan Scrying]], [[Lotus Petal]] – Since Rainbow Depths is trying to assemble a specific combo they dedicate several cards like [[Sylvan Scrying]] and [[Crop Rotation]] to find the missing pieces. They also use [[Lotus Petal]] and [[Elvish Spirit Guide]] to accelerate the combo. This allows their deck to be pretty consistent and fast.
[[Thoughtseize]], [[Duress]], [[Inquisition of Kozilek]] – Rainbow Depths plays eight discard spells, and the benefit of discard spells is they can be used both proactively and reactively. If our hand is faster, they can be used to slow us down, or they can be used to take a [[Chain of Vapor]] to protect their [[Marit Lage Token]]. Against all decks that play discard spells, it’s important that we protect our important pieces, like playing out our artifacts or putting a key spell on the top of our library.
[[Stifle]] – [[Stifle]] is usually a card we see out of [[Delver of Secrets]] or other tempo decks as a way to counter a fetchland to set the opponent back a turn and to prevent the opponent from getting all the colors of mana, but that’s not why Rainbow Depths plays it. They play it as a way to counter a [[Wasteland]] activation. It can be used to counter fetchlands, but [[Wasteland]] is so good at disrupting the combo and being able to counter it is crucial.Deck List
