Imagine the struggle of playing these cards on a small table
By either building a deck full of Giants or using cards like Maskwood Nexus to your advantage, Realm-Cloaked Giant becomes more like Plague Wind for five mana than Wrath of God
They let you look at the top card of your library at any time, play lands, and cast Bird spells from there , and, most importantly, they double-trigger abilities that fire when a land or Bird you control enters the battlefield
The opposite is also true: the better the individual creatures are, the weaker the tribal rewards need to be to convince you to play a lot of them
I remember even trying to trade food stamps for theirs and now as an adult who has saved every penny he has made being able to enjoy something that Ive loved since childhood now as a grown man is like buying back a piece of something I could never have, its not about the material its about the experience. Thats what we mean regarding the value of nostalgia
