"Cattle Call" Rating Score by お留守番

I have an RR Deck so I'm biased.
A card that activates by sending a beast-type monster from the extra to his GY as a cost, and puts out a beast-type monster from the EX.
It looks like it's compatible with Iron Beast, but the effect disappears, so it's not a good match. They don't need to use that much because they're going to be ex.
Lunalight seems to be good because it can produce fusion materials, but I think "Lunalight Kaleido Chick" is not good enough.
As far as I can think of, RR is a good match.
A similar effect is "Raidraptor - Last Strix", which prevents damage, but can be easily searched for with "Raidraptor - Nest".
However, "Raidraptor - Nest" is a basic deployment card considering the activation conditions, and it is probably after the 3rd turn to aim for the last strike.
This card is more convenient when attacking with a larger RUM even though it cannot be searched.
It's also a Quick-Play Spell, so even if you get hit with a Effect Veiler or Infinite Impermanence when the effect of Raidraptor - Tribute Lanius is activated, you can sacrifice escape. It doesn't make sense for Urara to get shot at the time of summoning though!
As a drawback, it is easy to rot if the rank RUM is not drawn, and even though it is easy to cause card accidents due to the convenience of stacking RUM, it is even more likely to occur.
RUM can be searched if it can be expanded to The Phantom Knights of Rusty Bardiche, so it's okay if it's in your hand while it's expanded.
In general, RR seems to be a good match, and it cannot be searched and accelerates accidents, but it is a card that has good compatibility with aggressive RR and if you want ATK.
