What spell cards target a player?

Answer 1

'Targeting' a player is not something that's ever been considered before in Yu-Gi-Oh, until Mystical Refpanel was released.

From the rulings on Mystical Refpanel, a card that targets a player will do the following;

Increase 1 player's life points,

Inflict Direct Damage to 1 player's life points,

Allow 1 player to draw a card or cards from their deck,

Cause 1 player to discard a card from hand,

Modify the actions 1 player can take.

So cards that target will include Upstart Goblin, Into the Void, Pot of Greed, Mesmeric Control and Allure of Darkness.

Cards like Lightning Vortex, Monster Reborn, etc, do not consider to target a player. Mystical Refpanel could not be used, for example, to allow the opponent to switch whose monsters are destroyed, or who gets the summoned monster.

Since targeting a player is only mentioned in the context of Mystical Refpanel, it should be noted that a card effect that does one of the listed effects, but does something else too, cannot be altered with Mystical Refpanel. So it cannot affect Solar Recharge.
