Heroes VII

But there is no "Astral Gate" spell. I can't imagine how to play cards of "incredible" size without this spell.

Astral Gate is a real headache. In the fifth game, it's banned on 50% of the maps because it breaks the logic of the scenarios. Plus, the rules constantly have restrictions on its use because the spell allows you to jump over guards without defeating them.
So, I'm not against the fact that this spell was removed. In my humble opinion, it's actually better without it. I haven't studied in detail what spells are actually in the game, but I must say that I would still like to see the "Portal to Town" spell in the game; it's not as overpowered, but it does make life easier. Although it could be in a weakened form (in the fifth part, for example, the portal to town only transports you to the nearest town, without any signs with the possibility of choosing, as in the third game on expert difficulty).
