Dolkka chain

field A: Evol~~ Dolkka
field B: master hyper, herald perfection, stardust dragon

the long chain:
master hyper --> dolkka--> herald--> dolkka--> stardust

is this chain ok?

the Dolkka controller say can't

but the other player, me & a few more watcher say can

Why it is not ok? And who is he?

It can happen, all of these effects in this chain are Speed 2.

Dolkka is able to activate multiple times in a chain, this means that Dolkka can first negate Hyperion, then Herald negates that but Dolkka negates the negation. Dolkka also destroys which is were Stardust kicks in.

The point is, Dolkka can activate multiple times in a chain and all of these cards are the same speed so they can chain to each other.
