Second Bite is great for ramping up damage depending on how many Damage Counters your opponents Pokemon has, and it can even protect itself by using Crystal Ray
Thats made what were already some valuable chase cards Lillies Clefairy ex , Salamance ex , Ns Zoroark ex , and Ionos Bellibolt ex just as expensive and worth pulling as ever
Since it gives haste, it can be effective with cards like Archon of Cruelty and Grave Titan that have powerful ETB and attack triggers
Protection from a color, as seen on LEAs Ward cycle (including Green Ward), is the most common form of protection, but you can also get protection from creatures (Spirit Mantle), protection from player(s) (The One Ring), and even protection from everything (Progenitus)
Red was quite hard for me
One method players have of lasting an extra turn is by using Potion which recovers 20 HP from one of your Pokemon
