Guinan, Ancient AdvisorHow it works & interactions with other cards

What It Does

Guinan's ability targets every creature you control that entered the battlefield during the current turn. When you activate her ability for one generic mana and tap her, she places a +1/+1 counter on each of those specific creatures. Furthermore, if the total number of counters placed across all your creatures during this resolution is two or more, you get to draw a card.

Step-by-Step Resolution

First, you pay one mana and tap Guinan to put the ability on the stack. Upon resolution, the game checks which creatures currently on the battlefield under your control entered since the beginning of the turn. It does not matter how they entered (casting, tokens, or flicker effects). You place one +1/+1 counter on each eligible creature simultaneously. Finally, the game counts how many counters were just placed; if that number is two or greater, the draw effect occurs.

Common Mistakes

A frequent error is activating Guinan's ability before all intended creatures have entered the battlefield. Since the ability only checks for creatures present at the moment of resolution, any creature that enters later in the turn will not receive a counter. Additionally, remember that Guinan counts the number of counters placed, not the number of creatures. If a creature fails to receive a counter due to an effect like Vorinclex, Monstrous Raider, it might prevent you from drawing the card.

When to Play It

The best time to activate Guinan is during your post-combat main phase or the end of your opponent's turn if you flashed creatures in. You want to ensure you have at least two creatures that entered this turn to trigger the card draw. Because she requires tapping, she works best in defensive shells or decks that can untap creatures to use her ability multiple times in a single turn cycle.

Interaction examples

Expanding the Board

Solemn Simulacrum

If you cast Solemn Simulacrum and also create a creature token in the same turn, activating Guinan will place a +1/+1 counter on both the Golem and the token. Because you placed exactly two counters, you will also draw a card from Guinan's ability.

Type Synergy and Triggered Abilities

Roaming Throne

If Roaming Throne enters the battlefield naming 'Advisor', it will not cause Guinan's activated ability to trigger twice, as Roaming Throne only affects triggered abilities. However, if Roaming Throne and another creature entered this turn, Guinan's activation will place a counter on the Throne, count it toward the total of two, and successfully trigger the card draw.
