Dakmor Salvage and Drownyard Temple could be two more maybe lands. Dakmor can be replayed every turn. Drownyard can be as well with the added bonus of not using your land drop.

From a design perspective, it might make sense if the visit is just one block. However, the transition between Lorwyn and Shadowmoor did not occur on a day/night cycle.

I would definitely like to go back to Kaldheim but don't miss Capenna (just not the plane for me). Though, it doesn't seem enough time has passed to return yet.

However, I feel the real issue is single blocks. I understand the reasoning leaving the 3 block system (less $$ though my preferred) but we should get at least two block sets for larger storied planes. Aetherdrift? Duskmourn? Thunder Junction? Perfectly fine as a one offs, but for reasons stated above, Kaldheim and Capenna needed more space.

Not a fan of the 'just counter' or 'have removal' argument. It assumes you have Mana left open. It assumes you didn't remove a threat on the turn before a player casts Coalition Victory.

Just about every other 'I win' card either gives you a full turn like Happily Ever After or lets you know it's coming like Approach of the Second Sun. If you used all your mana actually doing things on your turn, Coalition Victory burns you. It just creates a tax against non-five color decks. Now they have to assume if the WUBRG deck has 8 Mana, they can just win (which isn't that fun).
