Maybe I’m missing something but I’m pretty sure Tsukiko made a mistake. After making Barkion, she could have summoned Mole Cricket from her GY to tag into Camelia and search Blessing with Sacred Tree’s non OPT effect and sync’d into a 5 or an 8 or simply hold the blessing with Camelia on field to summon back Mole Cricket to tag into Horn Needle or Sunflower on Shiori’s summon, which would have played around the Fire Fist card.
Also, even though I play Naturia on and off, I forget how weird all the cards look. They’re literally just shots of normal flora and fauna with giant anime eyes.
