Sun Titan rulings:
2021-07-23: You can look at the top card of your library whenever you want (with one restriction; see below), even if you don't have priority. This action doesn't use the stack. Knowing what that card is becomes part of the information you have access to, just like you can look at the cards in your hand.
2021-07-23: If the top card of your library changes while you're casting a spell, playing a land, or activating an ability, you can't look at the new top card until you finish doing so. This means that if you cast a spell from the top of your library, you can't look at the next card until you're done paying for that spell.
2021-07-23: Galea, Kindler of Hope doesn't change when you can cast Aura and Equipment spells. Normally, this means during your main phase when the stack is empty, although flash may change this.
2021-07-23: You'll still pay all costs for the spell, including additional costs. You may also pay alternative costs if any are available.
