| End Phase
Once Main Phase 2 (or Main Phase 1 if no Battle Phase was conducted) has been completed, the player proceeds to the End Phase (Japanese: エンドフェイズ Endofeizu). Any card effects that resolve in this Phase now take effect, such as "Change of Heart" or "Brain Control". The turn player gets to decide the order of their maintenance costs and/or effects of their cards that activate/apply at this time.
If the turn player has more cards in his/her hand than their hand size limit at this time, he/she must discard cards to the Graveyard until they have as many cards in their hand as their hand size limit. This action is the very last thing to happen in any End Phase.
If an action is to be taken "at the end of this turn", such as the expiration of the effect of "Effect Veiler", it is predictably the very last thing to happen in this Phase before the discard(s) for the hand size limit occurs (if any).
The End Phase is the only phase that cannot be skipped by a card effect (with the exception of the anime-exclusive card "Mischief of the Time Goddess"), unless the entire turn gets skipped.
