The reject would still cause Katakuri to take a life and go down to 1, which would still allow him to use Amaru. The only real way to prevent that would've been to leave him at 3 life, but that's also scary as he would've been able to safely play another 10c Big Mom that turn if he did.
@@kamikaze.33 yeah I get that which is why I said it didn't matter. But 2 things happen is that you avoid an attacker trigger and it forces the opponent to have reject +amaru. Again we know he had it and leaving him at 3 is too risky like you mentioned which is why i think the correct play is not swing the 7c borsalino.
Smooth brain deck. Imagine gain a life, remove a life from your opponent and put a 12k power character in game.. Or remove a life from your opponent for just 4Don
