Its better to give
Like most Magic: The Gathering cards, the value of Cloud, Midgar Mercenary depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (Final Fantasy)
You could also form a more permanent alliance with another player, and funnel them the tools they need to take out the opposition so you can duel it out for 1st and 2nd
There are plenty of tribes to choose from, and these cards should slot into just about any of them
Meanwhile, Invasion of New Phyrexia floods the board with knights, and you gain an emblem that permanently gives all your knights +1/+0 and ward 1 once it flips into Teferi Akosa of Zhalfir
This also makes it easy to transform Urabrask into The Great Work
