Ok heres a quick question
lets say
player A : sets down 2 face down cards and ends his turn.
player b : draws card, activates heavy storm
**can player A activate the 2 face down cards like a chain?**
**lets say the 2 face down cards are jar of greed and waboku**
if its a chain, does player A still get a card from jar of greed and is he protected by wabokus effect even though heavy storm destroyed them?

You are able to get the effects of both of your cards. This is so because after your opponet activates Heavy Strom you then get the oppertunity to respond or chain. You can activate either one you want but then you would have to let your opponent have the chance to respond to your card. If they don't then you can proceed to activate your second card. The same process would keep occuring until both of you no longer wish to respond. Hope this helps.

omg that helps alot thankyou.. so this is why ppl prefers waboku over negate attack

Exactly. When a card is played, picture that it leaves a ghost immage on the field. That ghost immage represents the effect of the card. Ghost immages can only be taken away by negating the card entirely.

In the case of continous cards, immagine that they simply have their ghosts stapled to the card itself.
