This is familiar because it reminds me of the release of Horakhty, the Creator of Light, another OCG exclusive card
This card functions as a counterpart to the all-black Zekrom, forming a pair as the only two Black White Rares in the sets
Then during your opponents turn, whenever theyd activate a spell/trap/monster effect, you can simply detach an XYZ material of the same type to negate & destroy their card
For example, if player A taps an artifact for mana during their turn, and players B and C are the next players in turn order who control Treasure Nabbers, C's ability resolves before B and C gains control of the artifact
The 10 two-color combinations are: Azorius : Blue/White Boros : Red/White Dimir : Blue/Black Golgari : Black/Green Gruul : Red/Green Izzet : Blue/Red Orzhov : White/Black Rakdos : Red/Black Selesnya : White/Green Simic : Blue/Green Three-color combinations The 10 three-color combinations get their names from two different places
