This is where I'm gonna have to correct you slightly.
Spell Speed 1 can only be Chain Link 1.
Spell Speed 3 can chain to anything, but only a Spell Speed 3 can chain to it.
Monster effects also have spell speeds.
Spell Speed 1
- Ignition Effects (i.e. Rescue Rabbit)
- Flip Effects (i.e. Nobleman-Eater Bug)
- Trigger Effects (i.e. Number 96: Dark Mist)
Spell Speed 2
- Quick Effects (i.e. Dark Paladin)
In the case of Monster Effects,
Flip Effects and
Trigger Effects can be chained to each other on ONE condition: They're activated at the same time. (i.e.
Mystic Tomato attacks another
Mystic Tomato, or
Swords of Revealing Light reveals 2 or more
Flip (Or Psuedo-Flip)
Effect Monsters.)
At the same time, there is 1 type of Monster Effect that does NOT have a Spell Speed. That would be
Continuous Effects such as
Jinzo and
Gachi Gachi Gantetsu. They can neither start a chain nor continue a chain. They just simply exist.
