While discarding a creature is a downside and adds a real cost to Dokuchis effect, it plays nicely with cards like Wonder and Malevolent Hermit if thats your jam
It can also slot into existing Darkness decks, such as Darkrai ex, as well as Poison Nihilego decks
Overall, the card is a unique spell that has occasionally seen play in tier 0 formats and is among the best holiday-themed cards ever printed
(I do wish this wasn't at the expense of the Charizard art, but hey, the Zard can't win 'em all.) Artist Misa Tsutsui utilizes the rather pattern-based background motif of Radiant Pokmon cards well, showing that there can be more detail than just a color effect
Connive allows you to draw then discard a card, and if you discard a non-land card, you may put a +1/+1 counter on that creature
The Knights are decent by themselves, though, but together, they become extra valuable
