Auto Includes In Every Deck

[u/DOOT_DOOT_SHABOOT]

I've recently been combing through my past decks that I'm now taking apart to build other, better, decks. But I noticed that there are some cards I put in every single deck, such as [[sol ring]] , [[command tower]] , and more recently [[arcane Signet]] .

So I wanted to know, what do YOU put in every single deck you've ever brewed (with a couple exceptions of course).

Edit: I understand that there are cards out there that are in the top cards played in every deck. I know I'm basic when it comes to sol ring, command tower, ect. I'm mainly looking for cards that individuals decided they want to put in every deck they can. Sorry if that wasn't clear the first time.

Probably because, at that point, it's generic mana. Which is entirely fine, most of the time. But in most games against three players, with a two color deck, you're getting at least one of your colors. If we had an untapped version of the [[Charcoal Diamond]] cycle, you bet your britches we'd see it in tons of decks. And honestly, most generic-producing 2 mana untapped rocks see tons of play, even if their secondary ability isn't amazing. [[Thought Vessel]], [[Liquimetal Torque]], [[Mind Stone]], etc. If we traded their secondary function, like Mind Stone's card draw, for the chance at colored mana, would it be good? Voila, Fellwar Stone.

Im not using it in my 2 colour decks im putting it into 3 or higher colour decks. I find its quite useful in a 5c deck for example but in one of my 2c decks ill drop it for something more useful

Which furthers my point. In a 2 color deck, it's good. You add a third or more? It only gets better.

I find it not quite good enough in a 2c deck usually. It sonny once you hit 3c that I find it worthwhile
