Lizard Wizard (Card that fills a specific niche)

[Tinkerer]

 

This card is also treated as Spellcaster-type while on the field or in the Graveyard. Once per turn, you can change this attack position card into face-up defense position; add 1 Reptile-type monster from your Graveyard to your Hand.

 

...And that niche was a level 4 monster that supports Reptiles and has 0 DEF.

 

Its Type and Attribute were also taken into consideration: as a Spellcaster, it opens up Jigobyte's Special Summon condition which makes it a 1-card XYZ if it grabs Jigo with its own effect. As a LIGHT, it can be set-up with Brilliant Fusion (which is also what I was aiming for).  Also, since it's both a LIGHT and a Spellcaster, it can be Summoned off of Ties of the Brethren in/with Performages.

This card seems kind of peculiar. Yes, it does fill a niche, but it also fills others, but remains so generic it doesn't completely fit. I would run this in a Performatile deck, but it doesn't really add much to Emem, or even to full Reptile decks, because it is a Spellcaster. I still like it though, and I feel there is potential somewhere, but I can't see it right now.

Heh, I had an idea on this card.  I changed it to Reptile-type, but I made replaced its self-boost effect with an effect that lets it treat itself as a Spellcaster while on the field/in grave.  This change allows it to be searched by King of the Feral Imps while keeping its previously stated uses.

I like this cards effects. It's a Masked Chamaeleon target. Combined with Kagetokage you have a Chaos option. It's a strong beat stick. You can track and MP2 get a search. And the Spellcaster part of him is a nice touch, giving you a lot of room for creativity, could use wonder wand after searching for Masked Chamaeleon. There are a few other strategies I can imagine this card being useful with as well.
