Phase 1 – Untap Phase
1. Untap all cards on the Battlefield. As with other trading card
games, "tapped" means that the card is turned 90 degrees to the
right, and "untapped" or "untapping" means that the card is
turned back to the upright position.
Phase 2 – Roll Phase
a. Roll a die (D20).
b. If a Pathogen number is rolled, play a card from the top of
the Pathogen Deck (it enters play tapped by default). By default, 20 starts out as the only Pathogen Number, but more can be added by various cards as the game progresses. For harder game modes, consider adding 10 as a default Pathogen Number, or even 5, 10, and 15 for Ultra-Hard gameplay.
Phase 3 – Draw Phase
4. Draw 3 cards. (Draw 7 cards if your player number
was rolled.)
Phase 4 – Main Phase
5. Do any of the following, in any order:
a. Play cards from your hand.
- Cards enter play tapped by default. (Cells, Organs, Lab Mice, and Pathogen Monsters typically enter the game tapped. Resources, Basic Resources, and Cytokines do not require tapping and are usually discarded upon use.)
b. Attack with cards on the battlefield.
- Cards on the battlefield are tapped by default when they attack. (While other games rely on a "tap" symbol, such as Magic: The Gathering, Immunomon does not use a tap symbol, and tapping is assumed by default.)
c. Go on the offense.
- Play a Pathogen Card when ready. It is suggested that
players wait until they have built a substantial army to defend against the
Pathogen Monsters before going on the offensive. During this phase, players may play the next card in the Pathogen Deck as many times as they like and attack with untapped cards. Once all Pathogen units have been defeated, the players win!
Phase 5 – Shuffle Phase
Shuffle any decks as required by card effects. This
phase can be done at the end of the turn.
Phase 6 – Pathogen Monster Attack Phase
