Some older creature cards, called leveler cards, have level up abilities that add level counters to them. These are not the same as class level abilities. Level counters do not interact with Class cards, and class levels do not interact with leveler cards. See rule 702.87, “Level Up,” and rule 711, “Leveler Cards.”

The effect that restarts the game finishes resolving just before the first turn’s untap step. If the spell or ability that generated that effect has additional instructions, those instructions are followed at this time. No player has priority, and any triggered abilities that trigger as a result will go on the stack the next time a player receives priority, usually during the first turn’s upkeep step.
