My ranking: Kinda Fun Adwal, Breaker of Chains Theyre an interesting Assassin/Pirate/Vehicle commander, but I dont think their effect is that interesting
That first ability probably sounds too powerful
The natural line of play here would be a first turn Black Vise, followed by a second turn Howling Mine
In Giada, you often want to be hitting Angels at all , being in mono white, so its more valuable than just drawing a card (which could be literally anything else)
Artifacts Okay, not actually a color, but I wanted to point out that artifacts already have carte blanche to do discard effects (a la Disrupting Scepter)
Not only does it provide a reason to play treasures, as being able to grant double strike to your dragons is a great ability to have
