Can I chain burn cards like “Chain Strike” to “Dimension Wall”?
Answer 1. That’s when you’re supposed to use it. 2. Yes. Chain Strike can go on any chain it’s legal to activate it on, so long as the same card hasn’t been put on the chain twice already. Dimension Wall is a normal trap; Chain Strike is a Quick-Play Spell. Both are Spell Speed 2. You can chain Spell Speed 2 cards together. 3. If you use Shell #1’s effect, get Shell #2 in your hand, and discard it for something, you can indeed use that second shell’s effect. 4. I do not believe so. 5. Technically, yes, though you’ll have to allow your opponent to search your deck to verify you don’t have Jurassic World.
