Missing the timing: cost✓
Dupe Frog is tributed for Substitoad's cost; Dupe Frog misses timing.
Dupe Frog is Tributed to pay the cost of Substitoad's effect. The last thing to happen is Substitoad Summoning a monster, so Dupe Frog's effect cannot be activated.
When can Chain Disappearance be used against Substitoad or the monster it Summons?✓
Substitoad is Summoned and tributes itself to Special Summon a Frog.
Chain Disappearance can be used in the Summon response window if the monster remains on the field. If Substitoad tributes itself for cost, it is no longer a legal target; you can instead chain to the summoned monster if it meets the condition.

● Like all ignition effects, this card's effect can be activated whenever you summon a monster. When you summon Substitoad, you can activate its effect using your ignition priority. When the "frog" monster is summoned, Substitoad's effect can be activated again, using your ignition priority.
●The ② applies to both players' "frog" monsters. If "Treeborn Frog" attacks an Attack Position Substitoad, the Treeborn Frog is not destroyed by battle, but Substitoad is.
●Tributing a monster is a cost. If you Tribute "Dupe Frog", Dupe's effect can't be activated.
