The game is heavily based on strategy, as deciding when to play a powerful champion card can be the difference between victory and defeat
Gut Shot is often too low damage per card to merit inclusion however Zap is simply too much mana for that kind of effect
It epitomizes blues identity and provides real value at a mana value cheap enough to be relevant for many formats while being color intensive enough not to go in every blue deck ever
You might get something good, or you might get something basic, its entirely up to chance but I appreciate the addition (and also the ability to snoop on other people to see what cards they are getting)
As Show of Confidence will trigger the Dragons treasure-making ability for each copy, you can use it early to make a ton of mana and keep churning through your deck
The initial cast costs one black mana, and then with it on the board, you can pay another single black mana and discard a creature card to return a creature from your graveyard to your hand, thus making it a strong recursion tool
