So this question occurred to me while I was playing a bit of YGOPRO, my opponent had summoned four Ojama tokens to my side of the field which are Light(Level 2, ATK 0, DEF 1000) and states that they cannot be used in a tribute summon.
I drew my trusty chaos form which summons blue eyes chaos max which is level 8, which could be all for of the Ojama tokens which were on my side of the field as the resolution cost of chaos form, however I was not allowed to do this, (I won the game anyway).
Because I have never heard of the rulings between tokens and ritual summons I thought I would check the wiki pages on this as it could be a good strategy to use in some ritual decks.
I check the token monster wiki which highlighted that tokens can be used for tributes unless stated otherwise and that the can be used for fusions, synchro and link summons but not xyz summons (because material doesn't count as being on the field and tokens only exist on the field). This page had no explanation of ritual summons.
Is this a grey area that not many people are sure of or have I missed something?
