If they are playable (look similar and easy to understand any unique mechanic) and not broken (a one drop 2/2 with flying haste double strike death touch wither)

Haha well yes I wouldn't want a degenerate card like that 😂

Mythic Hunter
- Cmc
Creature - Human
Mythic
3/4

First Strike
Protection from Mythic Rares
When Mythic Hunter enters the battlefield search target opponents hand, library and graveyard. Exile one target Mythic Rare card. If you search your opponents library shuffle it afterwards.


Here was one that I was brewing in my head lol

Edit: another one


Temporal Wurm
- Cmc
Creature - Wurm
Mythic
6/4

You may cast Temporal Wurm as you search your library as long as you sacrifice a forest in addition to its other costs.

Trample
: Exile Temporal Wurm with two time counters on it. At the beginning of your upkeep remove a time counter. When the last time counter is removed put Temporal Wurm on the bottom of your library. Activate this ability as long as Temporal Wurm is in your graveyard.
