Not only is Glorybringer a perfect target for Saheeli Rais -2 ability, as the token can be exerted without concern, but even Felidar Guardian can reset an Exerted Glorybringer to allow it to keep attacking and breathing fire all over your opponents battlefield
Counterspell is almost always the better choice
Their key Extra Deck monster however is "Swordsoul Grandmaster - Chixiao", an Extra Deck searcher able to search or banish any "Swordsoul" card from the Deck when summoned (who also has its own negation disruption effect), which enables further extension by searching for more "Swordsoul" starters or banishing a Trap to make a "Swordsoul Token", or to further strengthen the end board by searching a "Blackout" or "Emergence" (for it to search a generic Wyrm boss monster, like "Archnemeses Protos")
If he needs to finish the game with only one card in his hand, itll be harder for him to match his card with the other card he needs
Frankly, God-Eternal Oketra would be higher here were it not for the fact that most people play Blue and Black only
