Short, but somewhat preoccupying questions

[Azhur]

1.) When I wish for Doom Horror, why do I get it as a commander, rather as a unit, like all the other wished creatures?

2.) My prophet died 40 turns ago and I can't still make a new one. Why?

3.) Alt + Tab = when I come back to the game, the interface has turned rather "buggy" (same with Dom2). Anyone else has the same issue?

4.) With what spell do I call Seraph?

5.) Why is High seraph worse than Seraph?
