Your Séance token has haste although Séance doesn't grant haste.

I don't see a Giant Adephage token

• 7/7 Green Insect named "Giant Adephage"--Trample, "Whenever Giant Adephage deals combat damage to a player, put a token onto the battlefield that is a copy of Giant Adephage." (Giant Adephage)

• No creature's printed power/toughness may be greater than 9/9.
• Infinite combinations may not cycle through more than 9 times.
• No more than 9 counters of any one type may be on a permanent.

• The Commander tax applies only when you cast your Commander from the Command zone.
• The Commander tax only counts the number of times your Commander has been cast from the Command zone.

This applies to all Commander casting situations.

Remillo is responding to Kryptnyt's complex sequence of card moves by pointing out that, at any point where the Commander moves to either the Graveyard or Exile zone, its owner could stop the sequence dead by putting the Commander in the Command zone.

Quote from Remillo

For each time you cast it from the command zone, it costs 2 more to cast from the commander zone. If you cast it once, the next time it would be cast from the command zone, it would cost 2 more. If you cast it from your hand, reanimate it, etc, it would be for normal cost and would not count towards the cost additions.

With Kryptnyt's scenario, assuming you actually let it get destroyed or exiled and not return it to the command zone, it would only cost 2 to cast, assuming all of that ends up happening on the first time you cast it.

If your commander would be put into a Graveyard or Exile from anywhere, you can choose to put it back in to the command zone. So all of that would stop after the first Exile if the player were to choose that option.
