transformers mtg cards Magic: The Gathering Secret Lair: Transformers: Optimus vs. Megatron Foil you may have that player gain control of Slicer until end of turn Transformers Commander Set | Magic

This often meant I was going to get three or four copies of any card that might end up in a Commander deck

As PotatoPi said

Any time that I talk about ETBs and copying abilities, it almost feels obligatory to mention Dockside Extortionist but there are plenty of other great choices too

As a result, questing would give our opponent a free card, which is not worth the point of lore we get in exchange

I tried to take how narrow or wide an effect would be in addition to power level, but its hard to gauge

And from time to time, WotC makes a cool commander that buffs wraiths, only for players to find that there are only so many playable wraiths to begin with
