For instance, you pay an extra mana for the Beck half of Beck // Call compared to Glimpse of Nature, the Breaking half of Breaking // Entering mills two fewer cards than Glimpse the Unthinkable, the Burn half of Turn // Burn is one mana more than a Shock, Tumble of Rough // Tumble is worse than Pyroclasm, and so forth
My verdict: Few cards capture the feeling of a true finisher like this one

I probably drew 8 to 10 cards over multiple turns from using Shimmer Dragon's ability, so it definitely made a big difference in the game
Last, and in my opinion least, you have the Wildcard Bundle I personally don't recommend it, but if you'd like to go down that route you can buy as many wildcards as you can afford
