OCG Rulings

• Tributing 1 face-up Plant-Type monster is a cost.^[1]

• You can Special Summon a Level 5+ Plant-Type monster without Tribute.^[1]

• "Lonefire Blossom" can be Tributed to activate its own effect.^[2]

• If "Gozen Match" is activated, then you can only activate the effect of "Lonefire Blossom" if you have a FIRE Plant-Type monster in your Deck; you cannot activate the effect if you do not have any FIRE Plant-Type monsters in your Deck. However, if "Lonefire Blossom" Tributes itself and afterwards there are no monsters on your field, then when resolving the effect of "Lonefire Blossom" you can choose to Special Summon a WIND monster like "Tytannial, Princess of Camellias".^[3]

Previously Official Rulings

These TCG rulings were issued by Upper Deck Entertainment and have since been deemed unofficial by Konami.[4] They were previously considered official and can still be correct, as long as they follow the official gameplay rules, or unless Konami has issued a ruling that says otherwise.
