>Houdini
Equipment is a subtype and should be capitalized to reflect that. Also, Affinity? Hmm, not sure about this. You'll definitely have to playtest this to see how powerful it is.
>Ikora
Broken as fuck, trash immediately. Kazy, it is very easy to exile stuff to power up things like this. And frankly, I'd expect you to realize just how powerful this thing could get in Commander.
>Ionic
Already got feedback. Still, really think this needs Blue with self-mill.
>Ironcast Dragon.
Oh cool, it's like that Bane of Progress thing. Hmm, though it's more color intensive and doesn't hit as much. But it does have Flying. Hmm... maybe have it exile instead? Wait... maybe give the player a choice for each artifact destroyed, to put a counter on the dragon, or to get a gold token. Dragons love gold. No, the free mana would probably be a problem. Maybe have it do something with charge counters? I really love the concept, I just think it needs a little more. Though I might be wrong, IDK.
>The-Hulk
Yeah, I don't think that second ability flies. I guess you could make it get a counter on the draw, and it could become a copy of the creature, that would fix your problems. Though that also wouldn't be very Red. Actually, I don't see any Red in this now.
>Lighthouse
Not sure how I feel about this one. I think it has too much going on right now.
>Consonant Cur
So... a Red version of that BFZ elf, right? Meh. Not sure why it's a legend.
>Pledge
WTF is going on with that first ability?
>Tieflings, Polish based on the inscrutable names
I wish the Black ability did something on its own. It's absolutely a slave to the Red ability. Not sure what to replace it with though. I guess you could have Red grant D-Strike, and Black give +1/+1.
>Shallow Grave
Seems easy to abuse. Also, not a fan of Threshold.
>Husk
Kazy, just copy Scion of the Ur-Dragon. Again, don't think that last ability flies, I think it just needs to copy.
