Even though your starting hand size is increased by one, nothing else about the pregame procedure changes. If you don’t take two or more mulligans in a multiplayer game, you won’t be able to "scry" before the game starts.
If there are additional costs to cast a spell, or if the cost to cast a spell is increased by an effect, apply those increases before applying cost reductions.

The cost reduction can apply to an alternative cost, such as a madness cost.
If the first spell you cast in your turn has {X} in its mana cost, you choose the value of X before calculating the spell’s total cost. For example, if the first spell you cast in a turn has a mana cost of {X}{U}, you could choose 1 as the value of X and pay {U} to cast the spell.
