The cleanest solution is to make sure there are some creatures the removal can't answer efficiently
If multiple other creatures you control enter simultaneously, you must still choose different modes for each instance of the triggered ability that's put onto the stack
Ovinomancer (Mirage/Visions/Weatherlight) Black and Red might get reusable creature kill, but those usually are the only two cards to have this resource
Pokmon Arceus V and its Trinity Charge attack work to power up any Pokmon V (including Pokmon VSTAR, Pokmon V-UNION, or Pokmon VMAX) you have in playwhether thats another Arceus V or VSTAR, or some alternate attacker, Trinity Charge ensures that your deck will have the Energy attachments it needs to keep its strategy flowing
It comes with the added bonus that if the original Dragon was legendary, the token isnt, so you can keep both in play
