It's definitely an interesting choice of Ink types, as Amber/Amethyst is really focused on being hyper aggro - meaning the player is going to race their opponent to 20 Lore and try to do it as soon as possible
That has some sauce, especially considering that this is the cheapest version of Amulet of Vigor you can put in the command zone, and you get access to all colors heck, Im wondering if this is a good Maze's End commander
This is widely regarded as the most powerful weapon in the game and has made multiple appearances in the series since
If you do decide to go that route, pirates won't be in short supply as quite a few, including some Captain Hook cards, have been introduced through the Steel ink color
Regardless of which half you have as your Commander, Meld cards should have the color identity of their front and back faces combined
Then if you control a creature with power 7 or greater, you may play the exiled card without paying its mana cost
