Yugo used the effect of "Crystal Wing" to destroy "Greedy Venom", but Yuri used the effect of "Greedy Venom" to destroy every monster on the field and inflict damage equal to their original ATK
You can only use this effect of "Destiny HERO - Dangerous" once per turn
Cyber Dragon isnt as powerful as it once was, but Chimeratech Fusions, Cyber Network, and other brilliant support means that tech revolving around this classic card/archetype can never really be counted out
You can even customise your half of the field with different backgrounds, from green fields to glowing lava - which look lovely - and equip a friendly monster as a companion to cheer you on from the sidelines
At the end of the day, both engines find easy ways to get Xyz material onto the field, then later, both themes unlock even stronger monsters such as Cyber Dragon Infinity
