The "Might and Magic" Starter Deck is an Amethyst/Steel build and "Tactical Teamwork" is an Amber/Sapphire deck
Arahbo, the First Fang is a typal lord that gives your cats a buff and pumps out tokens when your other (nontoken) cats enter, but youve only got access to white cats if you run it as your commander
You and that player each create X 1/1 green Elf Warrior creature tokens
Sin, Spira's Punishment Rarity: Rare TYPE: Legendary Creature SUBTYPE: Leviathan Avatar CMC: 7 Mana cost: USD: $0.33 EUR: 0.26 TIX: 0.02 EDHREC RANK: 9638 (7/7) Flying Whenever Sin enters or attacks, exile a permanent card from your graveyard at random, then create a tapped token that's a copy of that card
If you play your deck a few times and find that a card you were excited about doesnt work as well as you wanted it to, you can just take it out and try something else
Exiling and returning something to the battlefield to retrigger its enter effects is always powerfull, and Y'shtola gives you a way to do that for free every turn
