Power of Three

All units that cost 3 mana start with +1 power.

1. When Power of Three is active, any unit with a mana cost of 3 receives +1 to its attack power at the start of battle. 
2. Power of Three does not give a new attack type to units that do not already have one. For example, a 3-mana unit with no attack does not gain Melee, Ranged, or Magic damage from this Modifier.

Power of Three Strategy

Power of Three rewards careful use of low-mana units. A 3-mana unit with a useful attack type can become much more efficient when it receives extra power before the first round begins.

Consider using:

1. 3-mana units with strong abilities.
2. 3-mana units with Magic Attack, since Magic usually bypasses Armor unless another rule or ability changes that interaction.
3. 3-mana Ranged or Melee attackers that can attack safely from their position.
4. Buffs such as Inspire to further increase pressure.
5. Defensive tools to keep your boosted 3-mana units alive.

Important Notes

Power of Three only affects units that cost exactly 3 mana.

It does not affect:

• Units that cost less than 3 mana
• Units that cost more than 3 mana
• Archons
• Units without an existing attack type
• Units Weapons Trained by a 3 mana card that do not cost 3 mana themselves. 

Power of Three Modifier Interactions

1. Even Stevens will not appear with Power of Three, since 3-mana units have an odd mana cost.
2. Little League can make Power of Three especially important, since many eligible cards are already low-mana units.
3. Back to Basics removes abilities, but Power of Three can still make 3-mana attackers more dangerous through raw stats.
