When you have a companion in your deck, no matter if its best-of-one or best-of-three, itll occupy one of your sideboard slots the last one, to be more precise
Why do we play the best cards we have access to
While some people seemed to be underwhelmed by the fact that he copies abilities instead of spells, Im already seeing a lot of excitement from those whove cracked the code and figured out which abilities are just kinda broken when you copy them for all of your creatures
The third kind announces is 'Hidden Neon', and is unique for showcase frames in that it is only going to be available on a single card: Hidetsugu, Devouring Chaos
Golgari Grist, the Hunger Tide Grist is pretty easily the most powerful card on my list today, but Im a big enough fan of the card to go to bat for it
Pair it with: Ouroboroid (yes again, this is mandatory) Ozolith, the Shattered Spire as it is a counters deck mainstay The Earth Crystal (can you believe that Final Fantasy only dropped a few weeks back?) Bristly Bill, Spine Sower coz he can trigger add +1/+1 counters through landfall and his activated ability You can even warp it in if you don't want to spend the full four
