Deck recomendations for 2 new players

For some context i am not new to the game but for sure inexperienced. I am getting 2 people into the game and they seem to enjoy playing from what little we played. there are no game stores aroumd here so being meta isnt an issue. One person enjoys the monsters as continuos spells from crystal beasts so im thinking maybe centur-ion. and the other person seemed intreagued eith link summoning focused decks so im thinking d. link. What is the gameplan eith centur-ion after calamity has been banned and what id a decent way to find modern drsgon link decks and combos eith alternate starts.
