Sacrificing a Dofus

Nope. Both Punishment and Clinging to Life destroy the Dofus, these cards don't inflict damage on it. Thus it won't trigger Sir Flexington.

If you want to play Sir Flexington, I have this Sram deck "auto-mill" that I like a lot (though it is weak against aggro decks) whose goal is to mill (draw all of) your own deck, put Sir Flexington and use Second Wind to discard 4 cards from your empty or almost empty draw. It will trigger 1 by 1 damage on Dofus for each "overdraw". Be careful though, it does destroy your Dofus first before your opponent, so you ever need to inflict one damage through trap or curses. It will destroy Dofus from your right to your left, so if you have two fake dofus on your right it's also something to take into account. Below is a decklist for anyone interested (could be improved I think didn't play it that much).
If you have any more questions, I invite you to the Krosmaga discord where we're more available to answer them than on the forum : https://discord.gg/GdtfJ9K

no it not dmg, also it ignore all shields and immune effects

Ah thats a shame

ive got 890 purple dofus things and i cant work out what I need
was thinking light speed but not sure what else Might be useful

also lol, Yeah somebody done that to me, Killed my dofus by decking themselves while sire flexington was on the field haha >_<

 

Clinging to Life and Sacrifice triggers the Sacrier Palidr, cant remember his name, but the dude that deals 3 dmg to all enemies whenever a dofus is destroyed.

martyred hero? Thats awesome, do you know if they trigger jet the flying foot?

No they do not. Jet triggers on damage, and they do not deal any damage, only destruction.

cool, thank you all for the info, this has helped me make some descisions on what cards to create
now i just need to save to get the infinite cards i need
