Time Walk Five mana for Time Warp is a lot, but Time Walk lets you take an extra turn for a mere 2 mana
I agree that nowadays destroying is not as good as before, but still, a card that counters anything that destroys less than 3 cards, including most Counter Traps (except Wiretap, Debunk, THRiO, etc.) doesn't look fair
There are three kinds of cards, and each works slightly differently when played
Bonehoard Dracosaur is big and has first strike, and it gives you two cards to play each turn, not to mention treasures or extra 3/1 tokens
Although, there is a glitch where there is a small chance of less than fifty being added
The Traps provide the deck with non-targeting disruption of our opponent, either by stealing their monsters, destroying them, or negating their effects
