The untap step is the first step of the beginning phase. The following events happen during the untap step, in order:

• All permanents with phasing controlled by the active player phase out, and all phased-out permanents that were controlled by the active player simultaneously phase in.
• The active player determines which permanents controlled by that player untaps, then untaps all those permanents simultaneously. (The player will untap all permanents he or she controls unless a card effect prevents this.)

No player receives priority during this step so spells or abilities cannot be played. Any state-based effects or triggered abilities that happen during this step are delayed until the upkeep step.

From the Comprehensive Rules 302. Untap Step 302.1. First, all permanents with phasing that the active player controls phase out, and all phased-out objects that the active player controlled when they phased out simultaneously phase in (this game action doesn’t use the stack). See rule 217.8, “Phased Out,” and rule 502.15, “Phasing.” 302.2. Next the active player determines which permanents he or she controls will untap. Then he or she untaps them all simultaneously (this game action doesn’t use the stack). Normally, all of a player’s permanents untap, but effects can keep one or more of a player’s permanents from untapping. 302.3. No player receives priority during the untap step, so no spells or abilities can be played or resolved. Any ability that triggers during this step will be held until the next time a player would receive priority, which is usually during the upkeep step. (See rule 303, “Upkeep Step.”)
