DESCRIPTION
i know that most people are going to automatically reject what im going to say, but gw tokens has been a very powerful deck for me, and i believe it is fairly competitive. (as soon as people see this word not attached to a net deck, let the insults fly, eh?)
but token armies are extremely powerful for a number of reasons:
1. tokens combined with an overrun ability can easily overwhelm an unprepared opponent.
2. tokens are ideal chump blockers and deter attackers.
3. token armies arent hurt badly by target removal. (lightning bolt, go for the throat, etc. will only kill one of the 5 or 6, which isnt that great for them)
4. elspeth tirel does a one-sided day of judgement and lives to create more tokens or give nasty amounts of life.
the only problem i have ever encountered is the dreaded pyroclasm-slagstorm-day of judgement, but i have always been able to recover from these fairly easily. against decks capable of running these spells i avoid going all in until i can get them to throw down their wipes. plus, ajani can get cat tokens out of pyroclasms range before they get a chance. thopter assembly is probably the best anti-wipe that i have because it gives me tokens the next turn and will the wait safely my hand until the next boardwipe.
i dont think i missed anything, basically ramp and play one of the token generators, then use a planeswalker to boost them and swing.
