Sub-Divide

[Toffee.]

[spoiler=V1]

Discard 1 monster with a Sub-Type. Add from your Deck to your hand 2 monsters with the same Sub-Type as the Discarded monster, but with different Attributes from each other and the Discarded monster. You cannot Special Summon during the turn you activated this card. You can only activate 1 "Sub-Divide" per turn.

You cannot Special Summon monsters during this turn, except ones with the same Sub-Type as the Discarded monster. You can only activate 1 "Sub-Divide" per turn.

Obviously I had Spirits in mind when I made this.
However, because I couldn't come up with a decent Spirit reference, because it's basically required for those cards, I decided to just say fuck it and go the extra mile and make this more outlandish then it was already intended to be(As well as making the artwork sillier).

Pros to this card are the fact Spirits don't give a shit about any of this card's drawbacks and can very easily make use of it. It lets you mix and match your Tuners/etc, provided you don't mind loosing the ability to Special Summon that turn. Yes, you can search Rituals/etc, although I highly doubt you could make a deck that can use that many different Ritual monsters.
Can also search out Toons, which is another bonus =D

EDIT 1: Changed the drawback.

I like this card for being silly and potentially relevant at the same time. It's some kind of Onomatopair variant for sub-types, and support for sub-types i general is cool. The "different Attributes" retriction hurts its playability, but it is only fair in my opinion; otherwise we would see Shaddolls running this.

As mentioned in the OP, it should be splashable with no problems in Spirit and Toons decks, and also in Gemini decks and gimmicky, non-competitive Flip control decks with a wide array of Flips such as Ryko, Penguin Soldier, etc.

However, the "cannot Special Summon" clause could be a noticeable drawback in non-Spirit or Flip Decks. Considering the card is not as splashable, I think it could actually get away without such clause.

Updated OP.
 

Considering the card is not as splashable, I think it could actually get away without such clause.

It actually needs somewhat of a drawback, since Synchrons are now a thing again, and they could very easily abuse the fuck out of this. Since, you know, Tuner is a Sub-Type.

Anyway, current version lets Tuners be Special Summoned, if you Discard a Tuner, however... You could only really make Synchro-Tuners with them if you also used your Normal Summon. Though, the only real prominent ones would be Quickdraw and Unknown in this case.

Plus, this change makes more sense it can let Toons be more rampant with plays involving Mermaid/etc, while still being a hindrance to the potentially more dangerous other kinds of stuff you could search with this.
Also, to an extent, something like Performapals could get away with this, which is pretty silly.

Yes, I can see the risk of abusing Synchron/Tuners, but unless the Tuners you search can Special Summon themselves, you could hardly go Synchro crazy in the same turn you activate this card; at least in theory. You already pointed out the Unknown + Quickdraw combo in Synchrons , but to search for both you would have to discard a non DARK/WIND Tuner, and that would be... Jet Synchron, who apparently doesn't mind being discarded that much. So yeah, I agree: the card needs a cannot Special Summon drawback.

 

Anyways, the fix looks fair, and is a clever way of preventing the player from going Synchro crazy after searching 2 Tuners. A great idea.
