Cost is one of the rules in the Life Card Duel.
Under the tournament rules, a normal Life Card Master can only have 16 Soul Points per turn.
But now, every card Tan Song uses requires an additional 6 Soul Points, which is unbearable for anyone.
Tan Song fell into prolonged contemplation.
He was calculating whether he had enough cost to make his plays.
For a Life Card Master with a fixed strategy, a sudden increase in card cost is a very frustrating issue, as you might run out of cost halfway through and be forced to stop your play.
It's one thing to interrupt your play; the worst is to be stopped at the most awkward moment, like sending followers on the field to the graveyard, preparing to activate a Spell Card for a special summon, only to find out you're short on cost, leaving you with an empty field.
Tan Song is facing this very issue now.
After engaging in a chain twice with Shen Sui, he only has 6 Soul Points left. A little carelessness and he'd be blocked by the cost.
