Azoth2099 thanks for the suggestions!

I think I'm more inclined to include rocks than rituals, I am a green player at heart and always prefer continual rather than burst ramp! Thran Dynamo is definitely one I'll be looking at, but I've also considered Heraldic Banner and Throne of Eldraine as solid options. The biggest issue I'm having is generally what to cut for them, the same issue I have for most of these options. Any suggestions there?

Treasonous Ogre isn't one I'd seen before, I'm definitely interested in that. Birgi, God of Storytelling  Flip seems more relevant if I'm trying to cast more than 2 spells in a turn, which in most cases I'm not and even then, the payoff seems too small for what the deck does generally speaking, I.E. ramp into Lathliss, then overwhelm the field with every dragon dropped after. Even most of the artifacts and enchantments currently tend to have pretty immediate effect.

I do tend to prefer to have my lands hit the field, though, so Tectonic Reformation seems mostly situationally useful. I tend to need more land draws than action draws with my current high curve, as I'm usually only doing 1 or 2 spells a turn and they're 5-8 CMC. Gamble for sure I'll be looking into, but to be honest I don't regularly find myself looking for any specific cards in the deck, my Sarkhan's Triumph is usually just finding my Utvara Hellkite, so a "win-more" situation generally, but I could see using it particularly for something like Sol Ring early to ramp more consistently. For those same reasons I couldn't really see justifying Fervent Mastery or Reckless Handling. I like being able to plan, and the random discard would be bad enough with Gamble. And yeah, Imperial Recruiter is fantastic but not so much here.

Molten Echoes 100%, I totally spaced that one. Sneak Attack seems good as well but I'd been running in mostly casual circles so I hadn't seriously considered including it before. Mana Echoes=better Birgi? Absolutely interested in this one now, I'd forgotten it existed as well! I'll be honest though, the Underworld Breach+draw spells/wheels is definitely outside of my desired playstyle with the deck, I don't tend to need anything differently than what I have in hand other than making sure I have a good mix of mana/spells in practice. I am running the Blood Moon, mostly because I happened to open the fancy foil one! My playgroups don't tend to justify a Price of Glory and all of my cards tend to be about equal in value, so I don't mind a few getting countered here and there. It tends to be board wipes that are the most impactful to me, or repeated removal of Lathliss, Dragon Queen. Stranglehold does seem good though, I may pick one up.

As far as Universal Automaton, I avoid changelings where possible mostly due to personal preference. I play a lot of tribal decks and it always feels a bit like cheating haha. I use it in decks that want multiple tribes though, like Rin and Seri, Inseparable. I assume you suggest Wandering Archaic  Flip in monocolored to specifically cover what the chosen color can't do? I.E. a red deck and Naturalize? I could see it being good, but also giving my opponents the ability to choose doesn't tend to work out too well for me, they tend to focus fire me no matter the game because I play politics whether I'm ahead or behind.

Thanks again for the suggestions, and if you have ideas for what to take out please let me know!

As in, another Rin and Seri, Inseparable card

mudkipdude on Card creation challenge

Lucky Survivor

Creature - Elf

At the start of your upkeep, put one luck counter on ~. If this card has three luck counters on it, remove all luck counters and give it +1/+1.


Intentional wording there, so it can trigger multiple times if the game goes on long enough.

Challenge - create a card that goes with the story of Rin and Seri, Inseparable

Alright, sorry this took awhile. king-saproling, I brought up the infinite combos problem to my friend, I've just been waiting for him to get back to me, he's been doing finals so it took him awhile. Basically, just pretend that the card states that it's a cast trigger, not an etb trigger. Think similar to Rin and Seri, Inseparable, but for elves and humans. So, with that in mind, do you or TheOfficialCreator have any suggestions?

Again, sorry this took so long for me to reply to.

Cards like Felidar Retreat that create a cat creature wont trigger Rin and Seri, Inseparable because the cat has not been cast?

shadow63 on What tribes would you like …

1 year ago

Theast few years wotc has combined tribes that lacked a lot of support like cats and dogs with Rin and Seri, Inseparable and nightmare and horror with Umbris, Fear Manifest

I would like to see bird and griffin or griffin and archon mixed also insect and spider just makes sense logically I know they're arachnids but theres so many cards that stretch what an insect should be already. That I don't think itd be too much of a stretch
