All players in EBL Championships, including the Transnational and any Youth events, are required to have a fully completed Convention Card describing their system. Supplemental notes may be added in order to clarify or expand explanations.
For the European Teams Championships, all players in the Open, Women's and Seniors Championships will be required to submit their Cards in advance, by email in order that they can be downloaded by their opposing teams well in advance of such Championships.
Brown Sticker Conventions and HUM systems are permitted in the Open and Women's Series of the EuropeanTeams Championships (held in the even numbered years). It is a requirement that when a convention card containing BS or HUM systems is filed, the requisite Brown Sticker forms or, in the case of HUM systems the fully documented system file in English will also be required. All other European Championships (unless otherwise designated) are deemed to be Category 3 and thus HUM or Brown Sticker systems are not permitted.
Full information regarding the submission of systems will be contained in the Supplemental Conditions of Contest for the event.
Players should check the EBL Systems Policy to ensure that any convention / system they wish to play is permitted in the event in they plan to participate.
