Tinkermon-Petermon

This is an efficient swarm engine using [BT1-056] Petermon. At 5-cost he can revive or play Tinkermon, which is very memory-efficient. Assuming cheapest hard-play LV3 digimons are always played at 2-cost, Petermon is effectively a 3-cost LV4 digimon that revives (does not cost your hand size).

While there are other digimons (especially in violet/purple) that can revive very efficiently, this is the only revival engine in yellow. Furthermore, Petermon is the only LV4 digimon with a revival ability, other digimons in violet are LV6.
