I wanna run a Tira (promo) deck but I dont know where to start...... so if someone can help me and name some cards the would help me out, I need it

what I can suggest as a strategum for Tira*5 is to focus on either air/fire or death/fire because then you can give a majority of your attacks around 2-3 speed because the highest block mod is like 3-4 but that's what I can offer right now. as for the second ability... just either play it to get the assured victory with a powerful attack... but I'd mainly focus on the speed boost.

I was going to play death and fire but i dont know what attacks i should play

attacks, I would assume you should look into Donnovan's attacks from DS02 and then anything that has at least a block mod of +1 and then just average damage. speed won't be much of a hassle because you'll have block mods on every card then. but the most you could probably use her own E is twice to three times, depending how many attacks you plan on playing on your and your opponents.
