[Main] Draw 1 (Draw 1 card from your deck.) and trash 1 card in your hand
Chaos Ruler, the Chaotic Magical Dragon Milling cards has always been incredibly powerful with the myriad of graveyard effects available in Yu-Gi-Oh, being able to get a bunch of monsters in the graveyard all at once can give you a huge advantage
It's also an improvement over the Digi-battle card it originally came from, as the background has been expanded to more clearly show that it's in the air
On top of that, since it's made with Bahamut Shark as a material, you can use effect up to 2 times by combining Bahamut Shark + the Xyz Material that Bahamut Shark had, securing enough hitting points to aim for a turnkill even if there are additional monsters on the opponent's field
The Winged Dragon of Ra sadly got nerfed to hell and back with its abilities that actively contradict each other, which sucks because the anime version's ability had it gain attack strength equal to the monsters that were used to Tribute summon it
I have always disclosed restoration methods on cards I've sold
