One is colours, it is already in two and those are two of the weaker combo support colours for this style of deck
As for how all this will affect the game itself, Id say itll be pretty big stuff
We were so excited about the showcase treatment that we knew we had to create an Ugin showcase frame as well
Once this card is in the graveyard, you can trigger its effect by casting a creature that costs 7 or more mana, which is quite convenient
If you're interested, though, I'd preorder sooner rather than later
These cards are excellent in aggro decks as you rarely need to reach more than five mana (most winning aggro decks should end their curve at four mana, with Hellrider/Hero of Bladehold-type threats) so the ability to not draw dead on a land is a huge boon
