Did you know any hand that opens Kambi + any other way to a lv1 fairy (usually a Purrely) can guaranteed search both Heralds? Once you have a lv1 fairy on field with Kambi in hand, the combo goes as follows:
1. Kambi eff to summon from hand
2. Kambi eff tribute itself to summon Eva from deck and lock yourself into fairies
3. Overlay Eva with your other lv1 fairy to summon Shamoji Soldier
4. Activate Shamoji Soldier detaching Eva (either effect works but the LP gain is safer to play around your opponent drawing into a kaiju)
5. Trigger Eva in GY banishing Kambi from GY and Shamoji Soldier from field to search Orange & Green Light (can banish other light fairies from GY instead of Shamoji from field if you have them, but I usually prefer banishing Shamoji from field anyway so my lv1 Purrely doesn't get stuck underneath it)
Shamoji Soldier is here bc it's the only fairy rank 1 that exists (conveniently also light attribute) and is therefore necessary for the combo line. Its effect is irrelevant beyond the fact that it is always activateable and detaches a material.
