I have 2 wild tornadoes and two walls of disruption. Other useful cards i can put in my post-nerf deck to have 6 traps? And i have another question: trap cards that are equipped on monsters like metalmorph, kunai with chain etc... will trigger noble knights effects?
You don't want traps that have strict activation conditions because they clog your backrow and then you can't use glory. Try stuff like collected power and typhoon to activate Drystan.
What do you guys think about floodgate or paleo canadia?
As a defensive cards and to use with arfeudutyr effect
Just to add, about collected power, I believe we can target opponent monster also and as long as it is a non-warrior, thus the noble arms will be destroyed and can be re-equipped to drystan to trigger it's effect.
Floodgate. Canadia, Interdimensional Matter transporter (to banish a NK, destroy the equip and re-equip on Drystan). Do not usemetalmorph, kunai or any traps like thoose (they don't trigger NK effects).
