Notably, some of these cards are TCG premieres, for which we’ve just learned their Japanese name:
-Supply Soldier of the Indestructible Insects (無死虫団の補給兵, mushi-mushi dan no hokyuuhei) & Heavy Cavalry of the Indestructible Insects (無死虫団の重騎兵, mushi-mushi dan no juukihei)
For these two, the “Indestructible Insects” (無死虫団, mushi-mushi dan) is confirmed to be the same term used in the flavor text of Insect Knight (localized as “Indestructible Insect Invaders”). The name of the theme combines 無 (“mu”, not) and 死 (shi, death), to form a homophone for 虫 (mushi, insect). The last kanji being 団 (dan, group/party).

-Insect Invitation (虫だけエリアー, mushi-dake eriaa)
While it sounds very close to Insect Imitation, in Japanese it’s closer to Insect Barrier (mushi-yoke bariaa). The name would mean “insect-only area”.

-Denial Deity Dotan (拒神ドゥータン, kyoshin doutan)
This seems to be based on the otaku-culture term “同担拒否” (doutan kyohi). This is used to indicate that one does not wish to mingle with those that have the same “favorite” (character/idol/etc.) as oneself. The monster’s name modifies 拒否 (kyohi, denial) for 拒神 (kyoshin, rejection/denial + god).

-Phalaenop Sisters (胡蝶姉妹, kouchou shimai, force-read as ファレノプ・シスターズ, falenop shisutaazu)
This name was actually revealed earlier through their reference art.

-Release Brainwashing (洗脳解放, sennou kaihou)
As expected, it’s a very similar name to Remove Brainwashing (洗脳解除, sennou kaijo), with 解放 (kaihou, liberation/release) instead.
