IHATENAMES Good catch!

Blade of Selves exiles the tokens, so you won't get the proliferate triggers, just the counters.

+1 for the name of this deck alone! It's truly a gift.

I totally get the flavour thing! I rationalise it by seeing Miirym as being Clone tribal as well as Dragon tribal, but it's pretty tenuous :-D.

Earthquake Dragon is probably high up the list for cutting, as is Intet, Sprite Dragon, Dragon Turtle and Korlessa. I love Gale's Redirection type effects, but not sure about it in your deck (a bit expensive for what will most likely be used to defend yourself). I dunno, I'll be honest you have better dragons than I do, so filling the gaps with clones was fairly easy for me :-D

Another thought I had but forgot to mention is token doubling, I know doublers can be quite expensive if you don't have them, but Panharmonicon is relatively cut-price at the moment and it has a lot of synergy with the deck.

Appreciate you've already covered this in the discussion above, but I have to insist on clone creatures for Mirrym :-D

The dead card thing is not as much of an issue as you may think; your main target isn't one of the dragons in your deck, it's Miirym herself. Even though many of the clones will cause you to legend-rule away Miirym, she just ends up in the command zone ready to go again, and you end up with two copies of Miirym. You could potentially recast Miirym then for two more copies, and any future clones can target the non-legendary version. Any creature clone (i.e. not spells that create tokens) will do, but Spark Double and Sakashima of a Thousand Faces are the stars.

I don't own a Kindred Discovery, but I found Kiora, Behemoth Beckoner does much the same job for only 3 mana, and the temp ramp is a nice extra.

This deck really does what it says on the tin! Have you considered Syr Konrad, the Grim, seeing as you are milling so heavily? I know your 5-drop slot is a bit heavy, but this one seems like a killer based on your build.

Nice deck! I play a Bess, Soul Nourisher deck, and I reckon she'd be great in the 99 here (and Cadira in that deck). This is a fun-looking budget deck, hope it does you proud!

Good stuff. Well I would recommend any creature clones, even if they get legend-ruled, because they really do get out of hand. Enjoy!
