I've made the realization that the table above is perfectly valid and doesn't need adjusting at all. The distinction being that the table on the Battle Arena page advises us as to which dragons to use against a particular colour of dragon, whereas the blog table shows us what bonuses and penalties are applied when using a particular colour dragon.

E.g., fighting against a metal dragon yields no advantages or disadvantages (though hybrid metals might), whereas fighting with a metal dragon would provide advantages vs blue, gold and zodiac and gaining disadvantages vs red, diamond and rainbow.
