No offense, but ARE YOU CRAZY?!? Kaijus are way too good of a removal option, not to mention that they are special summon-able boss monsters with good attack. I highly doubt that they will give us Kaijus, at least for a very long time
Kaijus won't do 🔥 in duel links. The reason why kaijus were really good in the tcg is because they are the only out against unoutable boss monsters with multiple negation. Duel links have no boss monsters like that yet and offering to the doom already does a better job at dealing with boss monsters in duel links (since most of them have no protection)
Santa Claws would be the wisest choice, although I'm sure some scrubs might make some kind of mill deck with it. Kaijus tho? Hell no they're too op at this moment
I don't get why people think kaijus are too op for DL. They do nothing here except going minus 1 and giving your opponent a heavy beater. Unless something like master peace coming to DL I can't see them being useful at all.
