des deck yugioh Yu-Gi-Oh! 5D's Decade Duels Dark Ruler Ha Des Card Type YuGiOh Dark Revelation 1 Single

His business was limited by unreliable suppliers

(You can only equip 1 monster at a time to this card with this effect.) This card gains ATK and DEF equal to the ATK and DEF of that equipped monster

Relentless Assault variants tend to be win-more and they dont typically make their way into Cubes, but there are some Sacrifice synergies going on here with the morbid cost reduction and the +2/+2 and haste to give this card some wider applications

That its a gimmick

My only tip here is that, all things being equal and the game not coming down to finding a specific card, the two card pile will be way more attractive whether it is face-up or face-down
