Update: I have gone 3-2 with this deck so far. Lost to a Rat Colony deck and a Feather deck, and this deck is much slower than I assumed it would be. I would highly recommend a version similar to Strictly Better MTG's build, but with Golos added in as well.

Unlike Relentless Rats , Rat Colony frees you up to be able to use more different rats while still keeping the core of the deck intact. Rats like Pack Rat , Ink-Eyes, Servant of Oni , and Throat Slitter could be good includes although I understand if you feel this is too much of a move away from a rat colony deck. In addition, a few generic Tribal cards to increase the toughness of your rats could really help. Coat of Arms is really good but it affects everything and turns the board into a mess of math, Obelisk of Urd is much simpler on the board while still keeping your precious rodents from being killed by a single chump blocker.

That's easy. You would choose which creature would enter first or end up getting the Deathrender by choosing them in that order when the triggers resolve, since the triggers resolve one at a time.

Say you have Relentless Rats and Rat Colony in hand. You get the two Deathrender triggers, and decide you want Rat Colony to be the creature to end up with Deathrender equipped. When the first trigger resolves, you would choose Relentless Rats , putting it from your hand to the battlefield and equipping Deathrender to it. Then when the second trigger resolves, you put Rat Colony on the battlefield, and Deathrender unequips from Relentless Rats and attaches to Rat Colony .

This isn't just meant for random cards like Jellyfish and Pirate Ships, this is meant for cards that mechanically allow for any number of them in the deck. It's an entirely different play style and the deck is quite literally built around the one thing they do, be it growing to enormous proportions, tutoring out demons, or milling 12+ cards per turn.

Again, this has nothing to do with a deck being "rat tribal" or "advisor tribal" and everything to do about the fact you can run 24x of the same card to hone in on that one specific aspect.

While it may be a bit premature since we only have four cards that allow for any number of them in the deck and two of them are functionally identical ( Relentless Rats and Rat Colony ), the theme definitely is there and Wizards is clearly looking toward new design space.

Perhaps we will see cards of the same general "archetype" in different colors soon, perhaps not. Regardless, these decks do exist and can be made better. I feel it is worth a discussion at the very least.

So the tutorless hub idea got me thinking of other potential hubs that are currently not formed. I think I found one.

  • RCA

What is RCA? Well, like many hubs and deck archetypes, "RCA" is derived from the cards that inspired it; Or more specifically, the card's SUBTYPES that inspired it.

RCA stands for: Rats / Clerics / Advisors

I think we can all see where this is going. Each of these decks brings a unique twist to the deck building method; You pack your deck with as many of the same-named card as possible for maximum shock to the boardstate, whether it is a literal army of scaling rats, a cult of zealots willing to die for their lords, or an army of senators bickering over how best to play the game.

There are variances in these decks as well. While most Rats decks are mono-black, some run green for Genesis Wave to cheat a bunch out all at once. Most decks are going to be running Thrumming Stone , and are able to use the Cascade mechanic to cheat out even more for free. I'm sure other clever users will find more ways to cheat them out, too.

Clerics tend to favor either mono-black or Orzhov for recursion aspects and are a strong cEDH deck.

As for Advisors, I currently have an Oathbreaker deck that has been kicking tons of butts lately as a serious mono-blue mill engine in 1v1, and in Pods it can actually be used to mill MYSELF out so that I win by losing! Easier to mill out my 58 cards then it is to mill three other opponents out, haha.

It's literally just a matter of time before Wizards gives us cards of similar mechanical design in other colors, and we actually already have four; Rat Colony , who for a short time was sparking up as a Standard deck though it was unable to find a footing anywhere competitively.

So what does Tappedout think? Does RCA deserve a chance or should we wait to see if other cards are printed? :)

Cuickbrownfox1, Karrthus, Tyrant of Jund is fine to use because you can pick up dragons from other players to make a massive swing against somebody. Of course, it depends the decks of the other players, but it's the same when we talk about the second ability of Dragonlord Kolaghan . Very situational for both cases, but to compare other conditions, you may consider that the Kaarthus has a larger body, and even if it costs more, your mana base bends to Jund, so it's not necessarially a problem (talking about this deck). But yes, you have a good argument. I only consider the playgroup in a generic way, since I usually avoid changing the deck a lot and I hardly see decks as Rat Colony for a long time
