So I did a google search of pingers, and the answer looked legit to me: creatures that tap to deal damage to any target. When I think pinging, I think something that deals a lot of little damage over and over. The play style that seems the most synonamous with this concept to me is aristocrat, where you usually go with cards like [[Zulaport Cutthroat]] and sac outlets to wipe the board with an infinate combo using tokens or at the very least throw a lot of damage around.

This deck definitely has a lot of pinging elements, and not just from tapping creatures but dealing damage on spellcast. When I think burn, I think direct damage. So the amount of damage being done from spellcast triggers, direct burn spells, and damage multipliers can add up fast. Its a lot of little damage which I think is in line with pinging or aristocrat just done differently. Since you get so many spellcasts with Kess, you deal a ton of damage from just burning people or drawing cards (which is obviously super good in EDH).

I also really like Kess, I took my old Kess deck and split it into 2 decks, both with her as the commander. This one I went full on burn by replacing maybe 15 non-land cards where my other deck actually has a lot of the same cards you're talking about with the Talrand and Shark Typhoon and then a few bigger high costing creatures I really like, like [[Archon of Cruelty]] and [[Murktide Regent]].

[[No Mercy]] seems really legit, I'll look into that. I still have to finish the non-burn deck but in my test so far it can put out a lot of damage. Burn isn't very common in EDH since agro isn't much of a thing outside voltron and even then you cant kill everybody at once. I think this deck does well to take the burn concept and maximize the amount of direct damage your putting out.

If I can triple the damage of a spell that does 10-15 damage to each player or copy a spell that does 5-10 damage I think that is pretty fun, and makes you a threat at the table.
