Apex of PowerHow it works & interactions with other cards

The Power of Seven

When Apex of Power resolves, you exile the top seven cards of your library. You gain permission to cast spells from among those exiled cards until the end of the current turn. It is important to note that you cannot play lands from this group, as the card specifically uses the word 'cast.' Once the turn ends, any cards remaining in exile stay there indefinitely and are lost for the rest of the match.

The Mana Infusion

The most potent part of this spell is the secondary effect: adding ten mana of any one color. This only triggers if the spell was cast from your hand. If you cast it from your graveyard, library, or if it was copied by another effect, you will not receive the mana. This mana is added during the resolution of the spell, meaning it is available for you to spend on the seven cards you just exiled or other spells in your hand.

Timing and Restrictions

Apex of Power does not grant you special timing rules for the cards it exiles. You must still follow all normal restrictions; for example, you can only cast sorceries or creatures during your main phase when the stack is empty. Additionally, once you cast a spell from exile, it leaves the exile zone and moves to the stack; you cannot cast the same exiled card multiple times.

When to Cast Apex of Power

Because you lose access to the cards at the end of the turn, you should ideally cast Apex of Power during one of your main phases. This ensures you have the maximum amount of time to utilize the ten mana and the new spells. Casting it during your post-combat main phase is often safest if you need to see how the board state settles before committing to your new resources.

Interaction examples

Chaining Sorceries

Blasphemous Act

You cast Apex of Power from your hand, adding ten Red mana and exiling seven cards. Among them is Blasphemous Act. Since there are several creatures on the battlefield, the cost of Blasphemous Act is reduced. You can use a portion of the ten mana generated by Apex of Power to cast Blasphemous Act immediately to clear the board, then spend the remaining mana on other exiled spells.

Double Exile Effects

Soulfire Eruption

After resolving Apex of Power and gaining ten Red mana, you find Soulfire Eruption among the exiled cards. You use the mana from Apex of Power to cast Soulfire Eruption. This allows you to deal damage based on your library's top cards and exiles even more cards that you can play until the end of your next turn, effectively snowballing your card advantage.

The Copy Trap

If you use an effect to copy Apex of Power while it is on the stack, the copy will resolve first and exile seven cards. However, because the copy was not 'cast from your hand,' it will provide zero mana. Only the original spell, assuming it was cast from your hand, will provide the ten mana when it eventually resolves.
