Demon of Catastrophes A four mana 6/6 flying trample creature is certainly no joke, even with the drawback of having to sacrifice a creature to cast it
Your ideal use case is to cast Hour of Reckoning during your first main phase, then you attack into disadvantageous board states with whichever creatures you didnt tap to cast it
You can remove these counters to then bring lands back from your graveyard to your hand, which in turn gives you even more landfall triggers
Combine it with cards like Life and Limb, Sporoloth Ancient, or anything that lets you play more lands per turn for maximum value
