Since Beta 30.0, with the release of RG 03 and RG 04, when RG 01 dies, any Royal Guard on your board (except other RG 01's) gain Taunt. And with its already strong body, this becomes a big threat to the enemy as it can deal a lot of damage and they can expect more RGs to come, which would make the Dust very powerful.
- There used to be an easter egg which happened if both RG 01 and RG 02 were on the field. RG 02 would remove their chestplate and RG 01 would get nervous, just like in Undertale. They also gained a description (which was blank because they didn't have an ability before Beta 8.1 and the easter egg was removed before that update).
- Description when nervous: ''...''
- Beta 29.0 made the RG's part of the starting cardpool instead of Knight Knight.
