Note that the woodpecker would feed before it attacks, ideally. Not sure if this is possible codewise.
Yeah, I know these cards will both probably need balancing with regards to damage/health.
With one redwood:
Turn 1: 0 Damage
Turn 2: 4 Damage total, 19 health.
Turn 3: 12 Damage total, 15 health.
Turn 4: 24 Damage total, 7 health.
Turn 5: 40 Damage total, 0 health.
With two redwoods:
Turn 1: 0 Damage
Turn 2: 8 Damage total, 17 health each.
Turn 3: 24 Damage total, 9 health each.
Turn 4: 48 Damage total, 0 health each.
Aged:
Turn 1: 0 Damage
Turn 2: 4 Damage total, 23 health.
Turn 3: 12 Damage total, 17 health.
Turn 4: 24 Damage total, 8 health.
Turn 5: 36 Damage total, 0 health.
2x Aged:
Turn 1: 0 Damage
Turn 2: 8 Damage total, 20 health each.
Turn 3: 24 Damage total, 8 health each.
Turn 4: 36 Damage total, 0 health.
So yeah, obviously needs some balancing. Maybe make them deal the same damage to redwood as their attack, and change the giant woodpecker to 3 attack.
