yugioh slime cards YGOrganization (This card is still treated as a Trap Card.) Originally released October 2010. Yugioh Card “Mimighoul Slime” WPP6-KR021

For me, this constitutes Dp/HgSs/Pl through the first block of XY

And even though the artwork is suitably cute with them balancing their way across a fallen tree trunk, it's the special mechanic that really got me

There has also been some chatter on how this might interact with Crop Rotation based decks like Lands, but I have a feeling that it is not much better than Field of the Dead there, and the number of 0 and 1 mana cost artifacts those decks tend to run is very low (Mox Diamond and Pithing Needle primarily)

Update: 04/03/25 The release of Heatwave Arena is approaching rapidly and of ocurse, we have more card reveals for you which look absolutely amazing, particularly revolving around Cynthia & Garchomp with an SR & SAR reveal

As far as which one to take

You do want to ensure you dump at least two big things out with it however and so it will put some build constraints on your list should you wish to use it
