mtg exile card from hand MTGNexus Exile target creature or enchantment you dont control until target enchantment you control leaves the battlefield Connecting the Dots

These cards have the text 'Father & son' which allows you to use the pair as simultaneous commanders

I expect Repurposing Bay to work in a very similar manner

Crystal Fragments / Summon: Alexander Rating: 2/10 Short Sword is a fine card that you can sometimes play, but you wouldnt be excited to pick up

And it gets bigger: the last edition of the super selective MTG Arena Mythic Invitational had a prize pool of 900,000 (805,000)

A bit too Limited

Older TCGs may have higher price ceilings - nothing on this list can match the most expensive rare Pokmon cards or expensive Yugioh Cards - but there are some very valuable cards nonetheless
