van gogh pikachu pokemon card with Grey Felt Hat (Van Gogh) from Scarlet and Violet Promo Portrait with Grey Felt Hat Pikachu with Grey Felt Hat:

Theres dozens of legendary creatures that could lead a deck like that, so knowing where to start can be difficult thats why were looking at the best elf commanders in MTG

Wheel of Fortune and Reforge the Soul Red is a sad color because it does not have a lot of card-drawing in the raw

It is not until you are facing down 10 or more power that this starts to look potent and by then it will often be too late

Compare this to commonly played three mana removal spells like Generous Gift - that leaves behind much bigger 3/3 but can smoke lands too (Ditto Beast Within)

Then, at the start of your end step, you get to bring back a creature from your graveyard back to the battlefield, so long as its power is less than Mirkos

Hopefully one or more of these options gives you a few ideas for your own Jumbo Cactuar deck
