This sort of card usually needs a build around grade, because if you dont have enough ways to go really wide, you cant really play it but when youre in the right deck, this ends a lot of games This has bad base stats, but at least it can buff itself in a pinch
This cares about Commander and multiplayer, but not formats like Type Four, Highlander, or Five Color or Pauper, just Commander specifically and multiplayer generally
For five mana, Ultima is a rather on-rate boardwipe for Standard
This costs three mana to drop and equip, and gives the equipped dork flying, which is good because it's evasive and lifelink, which is good for the next ability
If you can get key effects you might need onto the board before using your Gamble you are in a better position to gain from it
